Description

A Method and an Apparatus for Developing Software

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application is related to and claims the benefit of priority to U.S. Serial Number 13/242,558, Attorney Docket No. 2112.1002, entitled A METHOD AND AN APPARATUS FOR DEVELOPING SOFTWARE, by Ahmad Raza, filed September 23, 2011 in the U.S. Patent and Trademark Office, the contents of which are incorporated herein by reference.

BACKGROUND

1. Field

[0002] This invention relates to the field of software development.

2. Description of the Related Art

[0003] Software development includes development of new software, maintenance of developed software, and quality assurance of developed software, wherein the maintenance includes a change and/or a modification in developed software, and wherein the quality assurance includes testing and/or debugging of developed software.

[0004] In software development, one of the biggest impediments is the large, many times prohibitive, amount of resources required for developing and maintaining even a small computer program. Moreover, the resources required for software development increase exponentially in proportion to the number of features required in a computer program. Also, the required resources can further grow astronomically for computer programs that must exclude any chance of an error and/or a malfunctioning.

[0005] At the same time, the expectations and requirements from software are increasing rapidly because of the swiftly increasing processing power and capabilities of computers. However, because of the limitations of available resources, such as, human resource, financial resource, time resource, technical resource, and the like, the art is still unable to develop, and utilize software to its full potential.

[0006] To address the above serious impediment, various technologies have been developed over time, but none has been able to effectively solve this problem so far. Such technologies include CASE tools, data driven programming, table driven programming, object oriented programming, CORBA (Common Object Request Broker Architecture), MDA (Model-Driven Architecture), RAD (Rapid Application Development), software factories, and the like. All these technologies have reduced, to some extent, the resource requirements for software development. These technologies have also enabled, somewhat, efficient utilization of the resources required for software development. Simultaneously, though, ever-increasing complexities, as well as exponential rises in functional requirements from software have meant that whatever benefits emanated from such technologies have not been enough to meet the growing demands from software.

[0007] In addition to the above mentioned technologies, many computer programs and development environments have been developed for reducing the resource requirement for the software development process. Such computer programs and development

environments include, but are not limited to, MS-VISUAL STUDIO, GNAT PROGRAMMING STUDIO, IBM RATIONAL APPLICATION DEVELOPER, POWERBUILDER, C++ BUILDER, XCODE, NETBEANS, DELPHI, LAZARUS, CRYSTAL REPORTS, MICROSOFT ACCESS, ORACLE DATABASE, and MICROSOFT SQL SERVER. While these computer programs and development environments have managed to automate a small number of mechanical tasks, they have not been effective in reducing the excessive resource requirements for software development.

[0008] Consider, for instance, a computer application which is required to comprise a couple of hundred reports which are desired to be based on MICROSOFT SQL Server database and are specifically designed for MICROSOFT ACCESS reporting engine and a letter size paper. In the prior art, each report, along with its required query, would have to be developed by a software developer. This process may take tens of thousands of hours of a skilled computer programmer. If the same reports are required to be ported to an ORACLE platform and CRYSTAL REPORTS with report layouts for an A4 size paper, the resource expenditure might be even greater than what was required for the original development.

[0009] The humongous and unmanageable resource requirement for software development is not only related to reports and queries, but also to every stage and aspect of software development. However, despite the availability of so many technologies, environments and applications, the prior art has been unable to meet the challenge of minimizing the required resources for software development to a desired, and an effective level.

[0010] Software development should, ideally, achieve three objectives simultaneously: maximizing features, ensuring highest quality, and minimizing software development resources. However, the prior art has failed to achieve all three objectives in conjunction; in every software development, one or more of these objectives have to be compromised.

SUMMARY

[0011] The major challenge in the prior art, that of minimizing resources, (man, technology, money, and time) required for software development, as well as in the maintenance and quality assurance of developed software, has been effectively met by the embodiments of the present invention.

[0012] According to an embodiment of the present invention, a new method for developing software is provided which empowers a machine (e.g. a computer) to function like a human software developer. A data token is defined, created and associated with a source code to enable the machine (e.g. a computer) to perform software development (enable the machine to generate or construct further source code, object code, and/or an object).

[0013] According to another embodiment of the present invention, a method is provided to streamline and simplify a source code which is required to develop software. A source object is created and utilized as the source code by the machine (e.g. a computer) to perform software development.

[0014] According to another embodiment of the present invention, a method is provided for creating a source object repository to store a source object. The source object repository enables easy creation, manageability, and reusability of a source object.

[0015] According to another embodiment of the invention, a method is provided for associating a data token to a source object in a manner that enables a computer to generate a complete source code by utilizing the source object and the associated data token.

[0016] Embodiments of the present invention provide numerous technical and commercial advantages. For example, according to an embodiment of the present invention, the time and resources required for software development are reduced substantially. According to another embodiment of the present invention, the available features and options in developed software are increased substantially.

[0017] The extraordinary benefits of applying the principles of the present invention will change the way software development is conceived and carried out. The inventive concepts and principles will create endless new possibilities and horizons - far beyond queries, reports, data entry forms, menus, business processing rules, help systems, exception handling systems, and the like -that are unknown and unthinkable in the prior art. [0018] Many more advantages will be readily apparent to one who is skilled in the art. BRIEF DESCRIPTION OF THE DRAWINGS

1. Definitions

[0042] Some of the terms used herein are not commonly used in the art. The discussion of the present invention utilizes some terms in a specific sense. Therefore, the following definitions are provided in order to ensure clarity, as well as to facilitate the understanding of the detailed description that follows. However, the invention, as set forth in the claims, should not necessarily be limited by these definitions.

[0043] A "data value" is a unit of data which comprises a piece of information and which requires at least one bit for a representation in a computer readable recording medium. Anything that can be stored in a computer readable recording medium is a data value.

7. A mnemonic is a source component of a source code block, which is a software component, of an assembly language. Component values which represent the mnemonic may include, but are not limited to, MOV, XOR, and CMP.

[0047] A "set of predetermined rules" 140 comprises one or more predetermined rules that are sufficient for constructing a software component. A set of predetermined rules is specified in terms of one or more source components, wherein each of the one or more source components is represented by at least one component value in a software component. Examples of a set of predetermined rules 140 may include, but are not limited to:

1. A set of predetermined rules for creating an SQL query, which is a software

component, according SQL-.2008 standard.

2. A set of predetermined rules for creating an SQL query, which is a software

component, which creates a table in an ORACLE database.

3. A set of predetermined rules for creating a form, which is a software component, in

MICROSOFT VISUAL BASIC 6.

4. A set of predetermined rules for creating a report layout, which is a software

component, in CRYSTAL REPORTS.

5. A set of predetermined rules for calculating the premium of a specific insurance policy in a software application, which is a software component.

6. A set of predetermined rules for creating a formula, which is a software component, in an EXCEL worksheet.

[0048] A "user" is someone who develops, installs, utilizes, and/or configures a computer program. A user may include, but is not limited to, a human being, a machine, and a computer program. It is possible that a user is also a developer of the same computer program that the user utilizes. [0049] A "data token" 152 comprises a set of data token rules 158 and is represented by a data value, hereinafter called token value 154, wherein the token value is processed on the basis of the set of data token rules, and then the result of the processed token value, which is also a data value, hereinafter called token result 156, is utilized for constructing a software component. The set of data token rules is specified at the time of defining a data token, wherein the set of data token rules comprises one or more rules which specify one or more manners in which a token value can be associated with a component value of a source component of a software component, can be processed, and/or can be utilized. The processing of a token value may include, but is not limited to, executing a function, performing a comparison, creating a component value, determining a manner in which a software component is constructed, identifying one or more component values for utilizing in a software component, or any combinations thereof. A token value may be determined by utilizing a parameter. A token value can also be associated with another token value. A token value can be nested in another token value of the same and/or a different data token.

[0050] Following are a few examples of a data token 152:

1. tknCompare is a data token 152 which is represented by a token value Comp(A,B).

When Comp(A,B) is processed according to its set of data token rules, the token result of the processed Comp(A,B) is utilized for constructing a software component. The token value Comp(A,B) of the data token tknCompare is processed on the basis of the following set of data token rules, wherein A and B are may be determined by utilizing two parameter values:

a. If A > B, then the token result is 1 ,

b. If A = B, then the token result is 0, and

c. If A < B, then the token result is -1.

In other words, in this example, the token value of the data token tknCompare acts like a function which returns one of the three possible values 1 , 0, or -1. In this example "A" represents total sales and "B" represents total cost of sales. tknCompare is utilized for determining a type of report that is to printed at runtime, if token result is 1 then a profit summary is printed, if token result is 0 then a breakeven report is printed, and if token result is -1 then a loss report is printed. In this manner, tknCompare enables a software component constructor 170 to generate an appropriate report on the basis of the values of "A" and "B".

2. tknRetrieve is a data token 152 which is represented by a token values tknDept(). A set of data token rules for processing tknRetrieve specifies that the token value tknDept() is processed in such a manner that it returns all department codes from a database table called tbl Department, hosted on a specific database server, which comprises department codes. The returned department codes, which represent a token result, are then utilized for constructing a desired software component, for example a crosstab SQL query.

Since number of departments may vary from time to time, tknRetrieve enables a software component constructor 170 to create an appropriate query, at runtime, on the basis of departments returned as a token result 156 when tknDept(), token value 154 of tknRetrieve, is processed.

JoinType is a data token 152 which is utilized for constructing a SELECT query, which is a software component. According to a set of data token rules of tknJoinType, the data token tknJoinType can be represented by one of the following token values, wherein each of the token values is illustrated along with a rule which specifies a manner in which the token value may be utilized:

a. 0 - No Join (a query will be constructed without any join because the first character of the token value is 0),

b. 1 - Inner Join (a query will be constructed with INNER JOIN because the first character of the token value is 1 ),

c. 2 - Left Join (a query will be constructed with LEFT JOIN because the first character of the token value is 2), and

d. 3 - Right Join (a query will be constructed with RIGHT JOIN because the first character of the token value is 3).

A token value 154 of tknJoinType may be retrieved by utilizing a parameter value 162 obtained from a user at runtime and an SQL query may be constructed by a software component constructor 170 accordingly. source object" 166 comprises: omponent value 146,

ken value 154,

ata value, which specifies:

a. an identity of a source object 166,

b. a meta data describing a source object 166,

c. a relation, order, and/or hierarchy among a component value 146 and a token value 154,

d. a relation, order, and/or hierarchy among a plurality of component values 146_n,

e. a relation, order, and/or hierarchy among a plurality of token values 154_n, f. reference to a component value 146,

g. reference to a token value 154,

h. reference to another source object 166, or

i. any combinations thereof, or

4. any combinations thereof.

[0052] A "software component constructor" 170 is a computer program which is sufficient for constructing a software component 142, or a part thereof, on the basis of a set of predetermined rules 140 and by utilizing a source object 166, a component value 146, a token value 154, a token result 156, or any combinations thereof, wherein a source object 166, a component value 146, and/or a token value 154 may be determined by utilizing a parameter value 162. A software component constructor may be a single computer program or a plurality of computer programs that are integrated and/or interfaced with each other. A software component constructor may adapt a set of predetermined rules, on which the software constructor is based, in a manner that no rule of the set of predetermined rules is violated to an extent that a software component cannot be constructed on the basis of the adapted set of predetermined rules. For example, a query builder, a software component constructor, which constructs SQL queries for DB2, MICROSOFT ACCESS, MICROSOFT SQL Server, ORACLE, and/or SYBASE, is a software component constructor. Another example of a software component constructor is a report creator which creates report layouts for CRYSTAL REPORTS.

[0053] A "source object repository" 168 comprises one or more data structures and is utilized for storing a source object 166 in a computer readable recording medium, wherein the source object repository is created on the basis of a data model which is suitable and sufficient for creating a source object repository that is suitable and sufficient for:

1. Compulsorily:

a. storing one or more source objects as structured and/or semi-structured data, and

b. identifying and retrieving a desired source object out of the one or more source objects.

2. Optionally, if desired:

a. implementing and maintaining, in a desired manner, a desired hierarchy and/or a desired relationship among all such source components which are comprised in a source object, b. implementing and maintaining a desired order among one or more component values belonging to a source component that represents the one or more component values,

c. utilizing a source object and/or a desired part thereof in another source object,

d. associating one or more data tokens with one or more component values of one or more source objects, and

e. any combinations thereof.

[0054] A data structure comprised by the source object repository may include, but is not limited to, a database table, a class, an array, a linked list, a variable, a multidimensional array, a multidimensional database, a conventional database, a flat file, a delimited text file, and a parameter.

[0055] A "computer program", as used herein, is defined as an executable sequence of instructions designed for execution on a processor either directly and/or via another computer program. The computer program may include, but is not limited to, a subroutine, a function, a procedure, an interpreter, an object method, and an object implementation in an executable application, an applet, a servlet, an executable source code, an object code, an ActiveX, and a shared library/dynamic load library. A computer program is also known as software.

[0056] The terms "a" or "an", as used herein, are defined as one or as more than one. The term "plurality", as used herein, is defined as two or as more than two. The term "another", as used herein, is defined as at least a second or more.

[0057] The terms "including/include/includes", and/or "have/having/has", as used herein, are defined as "comprising/comprises" (i.e., open language).

[0058] Creation, utilization, association, and/or processing of a data token, as used herein, is defined as creation, utilization, association, and/or processing of a token value of the data token.

[0059] Utilization of a parameter, as used herein, is defined as utilization of a parameter value of the parameter.

[0060] The headings in this detailed description have been inserted for ease of readability and have no interpretative role.

2. The challenges in software development: [0061] The main challenges in software development are minimization of:

1. resources (man, technology, money and time) required for development and quality assurance of software,

2. resources required to maintain developed software and its quality assurance, and

3. particularly, the time required to develop and maintain software, as well as ensure quality assurance, even if other resources (human, financial, and technical) are adequately available.

[0062] The prior art in software development has failed to effectively address and meet the above challenges in software development because of the serious limitations that have been discussed in the 'BACKGROUND' section.

[0063] It is to be noted that, in the current environment, the expectations and requirements from software are rising rapidly because of the rapidly increasing processing power and capabilities of computers. However, because of the scarcity of available resources, such as human resource, financial resource, time resource, technical resource, and the like, the art is still unable to develop and utilize software to its full potential.

3. The Causes of the impediments in software development

[0064] After extensive research and detailed analysis of a wide range of existing computer programs, as well as the existing software development technologies, methodologies, tools, environments, and applications, the inventor identified the following main causes of the prohibitive resource requirements for software development in the prior art:

1. The available techniques, tools, and options for developing software are generally time intensive even for a person who is skilled, well trained, and experienced in the art.

2. Despite the availability of many advanced technologies, comprehensive software development tools, debugging tools, and quality assurance tools, most of the development and quality assurance of software is carried out by human beings; some machine assistance is available but is insufficient and inefficient. It is recognized that software development by human beings has some inherent limitations, such as:

a. A human being cannot work around the clock and is limited by the speed at which he/she can operate.

b. Software development requires a high level of training and experience in the art. c. Trained and experienced developers are hard to find, and are very costly.

3. Many computer programs are very large and too complex and, therefore, require vast, sometimes prohibitive, amounts of resources for development, maintenance, and/or quality assurance.

4. Most of the predetermined rules for developing (writing) software components are designed in a manner that even a small change in a developed computer program may lead to an extensive change in the developed computer program; hence, additional resources are required for any change. In many cases, a change in the developed computer program may require even more resources than were originally spent for developing the computer program. The available technologies and software development tools for facilitating and augmenting this effort are either very complex or provide very little functionality.

4. What needs to be done?

[0065] After finding the primary causes of the impediments in software development, the inventor concluded that the following are required to address the above causes:

1. The contribution provided by a computer and/or a machine in developing and

maintaining a computer program, and/or in providing quality assurance, needs to be enhanced as much as possible.

2. The remaining contribution, which is left to be provided by human beings, needs to be further reduced, in addition to being streamlined and simplified, thereby substantially reducing the human resource requirements in terms of time, number, training, experience, and cost.

5. Inventive concepts and methodologies that address the challenges in software development

[0066] The major challenge in the prior art, that of minimizing the resources (man, technology, money, and time) required for software development, maintenance and quality assurance, has been effectively met by the inventor. According to an aspect of an embodiment of the invention, an inventive method enables a computer and/or a machine to function like a human software developer, and to perform most of the software development. Moreover, the inventive method also streamlines and simplifies the remaining portion of the software development left for human software developers.

6.

[0068] In the attached drawings, like reference numerals are used to refer to like elements throughout, and in the descriptions of the drawings, pertinent details have been set forth and explained so as to provide a thorough understanding of the present invention. However, it may be clarified that the present invention may be applied and/or utilized without these specific details..

[0069]

7. An embodiment according to an aspect of the invention (Fig. 1 A)

[0070] Fig. 1 A is an exemplary flowchart that illustrates as aspect of an embodiment of the invention.

[0071] According to an aspect of an embodiment of the invention, at operation 20, a source object repository 168 is created. A source code repository 168 is utilized to store one or more source objects 166„ comprising one or more token values 154_n and/or one or more component values 146„ which represent one or more indeterminable source components 148_n. A source object repository 168 is based on a data model 164 which is created for a software component on the basis of rules based upon which a software component is written and/or developed. By way of an example, and not a limitation, a data model for an SQL query will base on the syntax of the SQL query. By way of another example, and not a limitation, a data model for a report layout in CRYSTAL REPORTS will base on the object model for reports exposed by CRYSTAL REPORTS.

[0072] According to an aspect of an embodiment of the invention, a source object repository 168 is created on the basis of a data model 164.

[0073] According to an aspect of an embodiment of the invention, a data model 164 is created on the basis of a set of predetermined rules 140 of a software component 142 (a software source code) and by utilizing one or more indeterminable source components 148„. [0074] According to an aspect of an embodiment of the invention, following steps are taken for creating a data model 164:

1. A set of predetermined rules 140 is selected, wherein the selected set of

predetermined rules 140 is defined terms of one or more source components 144_n.

2. Each of the one or more source components 144_n is categorized into one of the following categories:

[0297] A token value 154, representing srcUseCnd 516, can be associated with a component value 146, which represents "table-name 472k", which is an example of indeterminable source component 148, and be processed in conjunction with a parameter value 162 of a parameter prmUseCnd 622, which is an example of a parameter 160. The result of the processed token value 154, which is an example of a token result 156,

representing srcUseCnd 516, is utilized to determine whether the component value 146, representing table-name 472k, is desired to be utilized for constructing a desired query or not. The token value 154, representing srcUseCnd 516, can be processed at the time of:

1. resolving a component value 146, which represents table-name 472k, and/or

2. constructing a desired query.

[0298] srcUseCnd 516 is processed on the basis of the following set of data token rules 158:

1. A component value 146, representing table-name 472k, is utilized if either:

a. a token value 154, which represents srcUseCnd 516, and which is also associated to the component value 146, representing table-name 472k, is either an empty string or a NULL value, or

b. a token value 154, which represents srcUseCnd 516, and which is also associated to the component value 146, representing table-name 472k, comprises at least one string value which is also comprised by the parameter value 162 of prmUseCnd 622. For example, if a token value 154, which represents srcUseCnd 516, and which is also associated to the component value 146, representing table-name 472k, is "abc.xyz", and the parameter value 162 of prmUseCnd 622 is "nop.xyz", then since the string value "xyz" is comprised by both the token value 154, representing srcUseCnd 516, and the parameter value 162 of prmUseCnd 622, therefore the component value 146, representing table-name 472k, will be utilized for constructing the desired query. As another example, if a token value 154, which represents srcUseCnd 516, and which is also associated to the component value 146, representing table-name 472k, is "abc", and the parameter value 162 of prmUseCnd 622 is "abc.xyz", then since the string value "abc" is comprised by both the token value 154, representing srcUseCnd 516, and the parameter value 162 bf prmUseCnd 622, therefore the component value 146,

representing table-name 472k, will be utilized for constructing a desired query. A comparison is always performed between the individual string values separated by a comma and such comparison is also case insensitive.

2. The component value 146, representing table-name 472k, is not utilized for

constructing a desired query if, either:

a. the parameter value 162 of prmUseCnd 622 is an empty string or a NULL value, but the token value 154, which represents srcUseCnd 516, and which is also associated to the component value 146, representing table-name 472k, comprises at least one string value, or

b. the token value 154, which represents srcUseCnd 516, and which is also associated to the component value 146, representing table-name 472k, comprises no string value that is comprised by the parameter value 162 of prmUseCnd 622. For example, if the token value 154, which represents srcUseCnd 516, and which is also associated to the component value 146, representing table-name 472k, is "abc.xyz", and the parameter value 162 of prmUseCnd 622 is "nop.rst", then since neither the string value "abc" nor the string value "xyz" is comprised by the parameter value 162 of prmUseCnd 622, therefore the component value 146, representing table-name 472k, will not be utilized for constructing a desired query. A comparison is always performed between the individual string values separated by a comma and such comparison is also case insensitive.

[0299] For the implementation of srcUseCnd 516, it is mandatory that either:

1. the token value 154, which represents srcUseCnd 516, and which is also associated to the component value 146, representing table-name 472k, must also be associated to all component values that are either utilized with the component value 146, representing table-name 472k, or are directly dependent on the component value 146, representing table-name 472k, or

2. the component values, which are either utilized with the component value 146, representing table-name 472k, or are directly dependent on the component value 146, representing table-name 472k, should be structured in a manner that, if the component value 146, representing table-name 472k, is not utilized for constructing a desired query, then the component values, which are either utilized with the component value 146, representing table-name 472k, or are directly dependent on the component value 146, representing table-name 472k, should also not be utilized for constructing a desired query.

[0300] Data token colUseCnd 518, which is an example of a data token 152, is represented by a token value 154 of a string type, which is either:

1. a NULL value, or

2. an empty string, or

3. a string value or

4. a list of comma-separated string values comprising at least two string values. [0301] A token value 154, representing colUseCnd 518, can be associated with a desired component value 1 6, which represents fldAla 472c, which is an example of an

indeterminable source component 148, and is processed in conjunction with the parameter value 162 of a parameter prmUseCnd 622, which is an example of parameter 160. The result of the processed token value 154, which is an example of a token result 156,

representing colUseCnd 518, is utilized to determine whether the component value 146, representing fldAla 472c, is desired to be utilized for constructing the desired query. The token value 154, representing colUseCnd 518, can be processed at the time of:

1. resolving a component value 146, which represents fldAla 472c, and/or

2. constructing the desired query.

[0302] colUseCnd 518 is processed on the basis of the following set of data token rules 158:

1. A component value 146, representing fldAla 472c, is utilized if either:

a. a token value 154, which represents colUseCnd 518, and which is also associated to the component value 146, representing fldAla 472c, is either an empty string or a NULL value, or

b. a token value 154, which represents colUseCnd 518, and which is also associated to the component value 146, representing fldAla 472c, comprises at least one string value that is also comprised by the parameter value 162 of prmUseCnd 622. For example, if a token value 154, which represents colUseCnd 518, and which is also associated to the component value 146, representing fldAla 472c, is "abc.xyz", and the parameter value 162 of prmUseCnd 622 is "nop.xyz", then since the string value "xyz" is comprised by both the token value 154, representing colUseCnd 518, and the parameter value 162 of prmUseCnd 622, therefore the component value 146,

representing fldAla 472c, will be utilized for constructing a desired query. As another example, if a token value 154, which represents colUseCnd 518, and which is also associated to the component value 146, representing fldAla 472c, is "abc", and the parameter value 162 of prmUseCnd 622 is "abc.xyz", then since the string value "abc" is comprised by both the token value 154, representing colUseCnd 518, and the parameter value 162 of prmUseCnd 622, therefore the component value 146, representing fldAla 472c, will be utilized for constructing a desired query. A comparison is always performed between the individual string values separated by a comma and such comparison is also case insensitive. 2. The component value 146, representing fldAla 472c, is not utilized for constructing a desired query if, either:

a. a parameter value 162 of prmUseCnd 622 is an empty string or a NULL value, but the token value 154, which represents colUseCnd 518, and which is also associated to the component value 146, representing fldAla 472c, comprises at least one string value, or

b. the token value 154, which represents colUseCnd 518, and which is also associated to the component value 146, representing fldAla 472c, comprises no string value that is comprised by the parameter value 162 of prmUseCnd 622. For example, if the token value 154, which represents colUseCnd 518, and which is also associated to the component value 146, representing the fldAla 472c, is "abc.xyz", and the parameter value 162 of prmUseCnd 622 is "nop.rst", then since neither the string value "abc" nor the string value "xyz" is comprised by the parameter value 162 of prmUseCnd 622, therefore the component value 146, representing fldAla 472c, will not be utilized for constructing the desired query. A comparison is always performed between the individual string values separated by a comma and such comparison is also case insensitive.

[0303] For the implementation of colUseCnd 518, it is mandatory that either:

1. the token value 154, which represents colUseCnd 518, and which is also associated to the component value 146, representing fldAla 472c, must also be associated to all component values that are either utilized with the component value 146, representing fldAla 472c, or are directly dependent on the component value 146, representing fldAla 472c, or

2. the component values, which are either utilized with the component value 146, representing fldAla 472c or are directly dependent on the component value 146, representing fldAla 472c, be structured in a manner that, if the component value 146, representing fldAla 472c, is not utilized for constructing the desired query, then the component values, which are either utilized with the component value 146, representing fldAla 472c, or are directly dependent on the component value 146, representing fldAla 472c, should also not be utilized for constructing the desired query.

[0304] Data token colReuse 520, which is an example of a data token 152, is represented by a token value 154 of a Boolean type and can comprise one of three possible token values: True, False and NULL. colReuse 520 is utilized in conjunction with a token value 154, which represents another data token tknMonth 524. colReuse 520 is to be associated with a component value 146 that represents fldAla 472c. colReuse 520 enables queryBuilder to identify a component value 146 that represents fldAla 472c, and it is desired to generate component values 146„ on the basis of token result 156 of tknMonth 524 and which is also associated with the component value which represents fldAla 472c, wherein the token result 156 of tknMonth 524 is obtained by processing the token value 154, which represents tknMonth 524.

[0305] For implementing colReuse 520, it is mandatory that the component values, which are utilized with a component value 146, which represents fldAla 472c, or which are directly dependent on the a component value 146 which represents fldAla 472c, are to be structured in a manner that all component values, which are either utilized with the component value 146, which represents fldAla 472c, or which are directly dependent on component value 146, which represents fldAla 472c, can be generated together with the component value 146, which represents fldAla 472c.

[0306] Data token tknAlias 522, which is an example of a data token 152, is represented by a token value "!", an exclamation sign without quotes, as specified by a set of data token rules 158 for tknAlias 522. The set of data token rules 158 for tknAlias 522 also specifies that tknAlias 522 is implicitly associated with the source component table-name 472k in such a manner that for each such new component value 146, which represents table-name 472k, tknAlias 522 is utilized for generating a new and a unique table/view alias comprising one or more alphabets. Since the association of tknAlias 522 is implicit, "I" (exclamation sign without quotes) is never utilized with any component value 146 that represents table-name 472k.

[0307] tknAlias 522 enables determination of a component value 46 for srcAla 472e, which is an indeterminable source component 148.

[0308] tknAlias 522 can also be associated with a component value 146 that represents fldNamCol 472b and/or fldXpr 472d, wherein the association with the component value 146 which represents fldNamCol 472b and/or fldXpr 472d is achieved by embedding "I"

(exclamation sign without quotes) in a component value 146 which represents fldNamCol 472b and/or fldXpr 472d. On processing, "!" (exclamation sign without quotes) will be replaced by a table/view alias, followed by a period, which was generated for a component value 146 which represents fldNamCol 472b and/or fldXpr 472d and is a source table/view of the component value 146 which represents fldNamCol 472b and/or fldXpr 472d, in accordance with the predetermined rules illustrated in Figs. 4B to 4R. For example, if for tbIA, a component value 146 representing table-name 472k, which is a table/view alias, and which is generated as a result of processing a token value 154, which represents tknAlias . 522, is "b" (lowercase b without quotes), then the following are a few examples which illustrate component values which are related to the component value tbIA and represent fIdNamCol 472b and/or fldXpr 472d, and which are also associated with "!" (exclamation sign without quotes):

1 . a component value "!fld_01 " will be "b.fld_01 " after processing of "!" (exclamation sign without quotes),

2. a component value "!fld_01 + !fld_02" will be "b.fld_01 + b.fld_02" after processing of

"!" (exclamation sign without quotes),

3. a component value "!fld_04 + INT(fld_05) - !fld_06" will be "b.fld_04 + INT(fld_05) - b.fld_06" after processing of "!" (exclamation sign without quotes), and

4. a component value "fld_09" will be "fld_09" after processing of "I" (exclamation sign without quotes) because "!" (exclamation sign without quotes) is not embedded in component value "fld_09".

[0309] Data token tknMonth 524, which is an example of a data token 152, is utilized for creating one or more component values that represent fIdNamCol 472b, fldAla 472c, and/or fldXpr 472d. tknMonth 524 is processed on the basis of a token value 154, which represents col Reuse 520, and a parameter value 162 of a parameter prmMthCnt 614, which is an example of a parameter 160. According to a set of data token rules 158 for the tknMonth 524, tknMonth 524 can be utilized in one of the following two formats:

1. %TknMth%, which can be embedded in a component value 146 representing

fIdNamCol 472b, fldAla 472c, and/or fldXpr 472d, and

2. %TknMth,argComp,argTrue,argFalse%, wherein tknMonth 524 is utilized with three arguments: argComp, argTrue and argFalse. This format of tknMonth 524 can only be embedded in component values that represent fIdNamCol 472b and/or fldXpr 472d. In this format, all three arguments, argComp, argTrue, and argFalse, are mandatory, and are required to be represented by a data value which is either a valid column/field name or is a valid expression. In this format, tknMonth 524 is utilized for determining the component values of the following indeterminable source components:

a. IIF 471f,

b. DECODE 471 n,

c. fldNamCnd 472g,

d. value 472h, e. true-result 472i, and

f. false-result 472j.

[0310] The processing of tknMonth 524 is done on the basis of a token value 154, which represents colReuse 520, and the parameter value 162 of prmMthCnt 614, which is an example of a parameter 160.

[0311] An exemplary set of data token rules 158 for colReuse 520 specifies that if a token value which represents colReuse 520 is a NULL value or False, or the parameter value 162 of prmMthCnt 614 is either zero or not defined, then tknMonth 524 is processed on the basis of the following part of the set of data token rules 158 for tknMonth 524:

1. If tknMonth 524 is embedded as %TknMth%, which is an example of a token value

154, then %TknMth% will be replaced with an empty string wherever it is embedded.

2. If tknMonth 524 is embedded as %TknMth,colCmpare,colTrue,colFalse%, which is an example of a token value 154, then %TknMth,colCmpare,colTrue,colFalse% will be replaced with colTrue wherever tknMonth 524 is embedded.

[0312] The set of data token rules 158 for colReuse 520 also specifies that if the token value 154, which represents colReuse 520, is True, and the parameter value 162 of prmMthCnt 614 is a positive integer, then the token value 154, which represents tknMonth 524, is processed in a manner that the component value 146 representing fldAla 472c along with all component values, which are either related to the component value 146 representing fldAla 472c or which are dependent on the component value 146 representing fldAla 472c, are utilized for constructing a desired query as many number of times as specified by the parameter value 162 of prmMthCnt 614. For processing tknMonth 524, the parameter value 162 of prmBegMth 616, which is an example of a parameter 160, is also utilized. The component value 146 which represents fldAla 472c along with all component values 146_n, which are either related to the component value 146 representing fldAla 472c, or which are dependent on the component value 146 representing fldAla 472c, are processed in a manner that all these component values are utilizable for constructing the desired query as many number of times as specified by the parameter value 162 of prmMthCnt 614. tknMonth 524 is processed on the basis of the following parts of the set of data token rules 158 for tknMonth 524:

1. If tknMonth 524 is utilized as %TknMth%, which is an example of a token value 154, then each iteration of %TknMth%, which results from the processing of the component value representing fldAla 472c, along with all component values that are either related to the component value representing fldAla 472c or are dependent on the component value representing fldAla 472c, is replaced by the first three letters of the name of the next month, starting from the month represented by the parameter value 162 of prmBegMth 616, and always continuing from Jan (for January) after Dec (for December) is reached. Here are two examples:

a. If the parameter value 162 of prmMthCnt 614 is 4, and the parameter value 162 of prmBegMth 616 is 3 (which represents the starting month of March), then the component value which represents fldAla 472c, along with all component values that are either related to the component value representing fldAla 472c, or are dependent on the component value representing fldAla 472c, will be utilized in the desired query 4 times, and %TknMth% will be replaced in all component values by:

Mar, on the first utilization of the component values, Apr, on the second utilization of the component values,

May, on the third utilization of the component values, and Jun, on the fourth utilization of the component values.

b. If the parameter value 162 of prmMthCnt 614 is 5, and the parameter value 162 of prmBegMth 616 is 11 (which represents the starting month of November), then the component value which represents fldAla 472c, along with all component values which are either related to the component value representing fldAla 472c or are dependent on the component value representing fldAla 472c, will be utilized in the desired query 5 times, and %TknMth% will be replaced in all component values by:

Nov, on the first utilization of the component values, Dec, on the second utilization of the component values,

Jan, on the third utilization of the component values, Feb, on the fourth utilization of the component values, and Mar, on the fifth utilization of the component values.knMonth 524 is utilized as %TknMth,argComp,argTrue,argFalse%, which is an example of a token value 154, then each iteration of

%TknMth,argComp,argTrue,argFalse%, which results from the processing of the component value representing fldAla 472c, along with all component values, which are either related to the component value representing fldAla 472c, or which are dependent on the component value representing fldAla 472c, is replaced by either an IIF 471f function or a DECODE 471 n function depending on the database for which the desired query is being constructed. In the IIF 471 f and the DECODE 471 n functions, argComp is compared with a value that is equal to the parameter value 162 of prmBegMth 616 at the first iteration, and the value will be increased by 1 for every next iteration, of the component values representing fldAla 472c, along with all component values, which are either related to the component value representing fldAla 472c or are dependent on the component value representing fldAla 472c. The value will start at 1 whenever the value goes beyond 12. Here are two examples:

a. If the parameter value 162 of prmMthCnt 614 is 4, the parameter value 162 of prmBegMth 616 is 3, and tkn Month 524 is represented by

%TknMth,colCmpare,colTrue,colFalse%, then

%TknMth,colCmpare,colTrue,colFalse% will be replaced by:

i. For MICROSOFT ACCESS:

1) IIF(colCompare=3,colTrue,colFalse)

2) 11 F(colCompare=4,colTrue,colFalse)

3) IIF(colCompare=5,colTrue,colFalse)

4) IIF(colCompare=6,colTrue,colFalse)

ii. For ORACLE:

1 ) DECODE(colCompare,3,colTrue,colFalse)

2) DECODE(colCompare,4,colTrue,colFalse)

3) DECODE(colCompare,5,colTrue,colFalse)

4) DECODE(colCompare,6,colTrue,colFalse)

b. If the parameter value 162 of prmMthCnt 614 is 5, the parameter value 162 of prmBegMth 616 is 11 , and tknMonth 524 is represented by

%TknMth,colCmpare,colTrue,colFalse%, then

%TknMth,colCmpare,colTrue,colFalse% will be replaced by:

i. For MICROSOFT ACCESS:

1) IIF(colCompare= =11 ,colTrue,colFalse)

2) IIF(colCompare= =12,colTrue,colFalse)

3) IIF(colCompare= =1 ,colTrue,colFalse)

4) IIF(colCompare= =2,colTrue,colFalse)

5) IIF(colCompare= =3,colTrue,colFalse)

For ORACLE:

1 ) DECODE(colCompare,11 ,colTrue,col False)

2) DECODE(colCompare,12,colTrue,colFalse)

3) DECODE(colCompare,1 ,colTrue,colFalse)

4) DECODE(colCompare,2,colTrue,colFalse)

5) DECODE(colCompare,3,colTrue,colFalse) [0313] Data token tknCurlyBrackets 526, which is an example of a data token 152, can be embedded in the component value 146 of the indeterminable source component whrXpr 472a. Data token tknCurlyBrackets 526 is represented by curly brackets, which are always utilized in a pair; an opening curly bracket, which is an example of a token value 154 of tknCurlyBrackets 526, "{" (without quotes) and a closing curly bracket, which is an example of a token value 154 of tknCurlyBrackets 526, "}" (without quotes). The opening curly bracket is always on the left side of the closing curly bracket. The curly brackets may be nested.

[0314] Figs. 5B and 5C illustrate an exemplary flowchart which explains an exemplary set of data token rules 158, specifying an exemplary processing logic, for tknCurlyBrackets 526. However, the exemplary flowchart does not provide any means for error checking and/or incorrect utilization of tknCurlyBrackets 526; throughout this exemplary flowchart, it is assumed that tknCurlyBrackets 526 is utilized appropriately.

[0315] The processing logic for tknCurlyBrackets 526 starts at operation 550a.

[0316] At operation 550b, whrXpr 472a, represented as "a target string" in the flowchart, is assigned to a variable EmbStr. In this example, tknCurlyBrackets 526 can only be utilized in a component value representing whrXpr 472a. However, tknCurlyBrackets 526 can be utilized in any other component value of a string type, if required and/or desired.

[0317] At operation 550c, the position of the last occurrence of "{" (without quotes) from the left side of EmbStr is stored in a variable Pos1.

[0318] At operation 550d, it is checked whether the last occurrence of "{" (without quotes) is found or not. If the last occurrence of "{" (without quotes) is not found, then the flow advances to operation 550e. Otherwise, the flow continues to operation 550f. The last occurrence of "{" (without quotes) will not be found in EmbStr only in one of the following two cases (assuming that the curly brackets are not utilized incorrectly):

1. A token value 154 representing tknCurlyBrackets 526 is not utilized in whrXpr 472a.

2. The processing of tknCurlyBrackets 526 is complete.

[0319] At operation 550e, EmbStr is returned and processing of tknCurlyBrackets 526 is complete.

[0320] At operation 550f, the first occurrence of "}" (without quotes) from the left side, after Pos1 , is located and assigned to a variable Pos2. [0321] At operation 550g, the string between Pos1 and Pos2 (characters at Pos1 and Pos2 are not included) is assigned to a variable DtaTkn.

[0322] At operation 550h, DtaTkn, which carries a token value representing a data token, is processed in a desired manner, and the result of the processed token value carried by DtaTkn is assigned to a variable TknResult. In this particular example, a parameter would be a result of the processing of the token value carried by DtaTkn. If the parameter corresponding to the token value of DtaTkn is found, then TknResult will comprise the found parameter. Otherwise, TknResult will comprise a NULL value.

[0323] At operation 550i, a variable Pos3 is assigned a value of (Pos2 + 1 ).

[0324] At operation 550j, it is checked whether the character at Pos3 in EmbStr is "}" (without quotes) or not. If the character at Pos3 in EmbStr is "}", then the flow continues to operation 550k. Otherwise, the flow continues to operation 550I.

[0325] At operation 550k, a variable Pos4 is assigned the position of the last occurrence of "{" (without quotes) just before Pos1 from the left side in EmbStr.

[0326] At operation 550I, it is checked whether TknResult carries a NULL value or not. If TknResult carries a NULL value, then the flow continues to operation 550m. Otherwise, the flow continues to 550n.

[0327] At operation 550m, TknResult is assigned a value: "1 = 1 " (without quotes).

[0328] At operation 550n, the string starting from Pos1 and ending at Pos2 (both Pos1 and Pos2 included) in EmbStr is replaced with the value carried by TknResult.

[0329] At operation 550o, it is checked whether TknResult carries a NULL value or not. If TknResult carries a NULL value, then the flow continues to operation 550 p. Otherwise, the flow continues to 550q.

[0330] At operation 550p, TknResult is assigned a value: "1 = 1 " (without quotes).

[0331] At operation 550r, the string starting from Pos4 and ending at Pos3 (both Pos4 and Pos3 are included) in EmbStr is replaced with the value carried by TknResult.

[0332] At operation 550q, the character at Pos3 is replaced with a space character.

[0333] At operation 550s, the character at Pos4 is replaced with a space character. [0334] At operation 550t, the string starting from Pos1 and ending at Pos2 (both Pos1 and Pos2 included) in EmbStr is replaced with the value carried by TknResult.

[0335] Data token tknltemCodeBegin 528 is processed in conjunction with the parameter value 162 of a parameter prmltmBeg 624. An exemplary set of data token rules for tknltemCodeBegin 528 specifies that tknltemCodeBegin 528 is represented by "itmBeg" (without quotes) and can only be embedded in a component value representing whrXpr 472a. When processed, "itmBeg" (without quotes) is replaced by the parameter value 162 of prmltmBeg 624.

[0336] A data token tknItemCodeEnd 530 is processed in conjunction with the parameter value 162 of a parameter prmltmEnd 626.

[0340] Fig. 7B illustrates a data model, which is an example of a data model 164, which is utilized for creating an exemplary source object repository 168, wherein the exemplary source object repository 168 is utilized for storing one or more source objects, along with one or more embedded token values, which are desired to be utilized for constructing a desired query. The exemplary source object repository 168, which is created on the basis of the exemplary data model 164, can be created by utilizing one or more data structures which may include, but are not limited to, a multidimensional database, a flat file database, a conventional database, an array, a matrix, a spreadsheet, a class, a comma-separated file, and a variable. The exemplary data model 164 is created in a manner that it is sufficient for creating an exemplary source object repository 168 which is sufficient for:

1. storing one or more desired source objects as structured and/or semi-structured data,

2. identifying and retrieving a desired source object out of the one or more desired source objects,

3. maintaining, in a desired manner, a desired hierarchy and/or a desired relationship among all the indeterminable source components illustrated in Fig. 4S,

4. maintaining a desired order among one or more component values belonging to srcld

754.

5. maintaining a desired order among one or more component values belonging to colAla 762.

6. associating all token values of the data tokens illustrated in Fig. 5A, either implicitly and/or explicitly, with one or more component values of one or more of the source components represented by the attributes illustrated in Fig. 7A, and

7. utilizing a source object and/or a desired part thereof in another source object.

[0341] The exemplary data model 164 comprises the following three entities:

1. Query 702.

2. Query Source 704.

3. Query Field 706.

[0342] Query 702 is the top level entity which is utilized to comprise information which is sufficient for identifying a source object and also information, which is applicable to the entire query. Query 702 comprises the following attributes:

1. qryld 732,

2. qryWhr 752,

3. qryGrp 512, and

4. qryUni 514.

[0343] qryld 732 is an exemplary attribute which is utilized in query 702 for the identification of a specific source object, qryld 732 acts as a primary key, and is utilized for uniquely identifying each source object. In query 702, qryld 732 is implemented as a string, and may comprise any valid component value of a string type. Since qryld 732 is utilized only for identifying and referencing a source object, there are no specific rules for a component which may be stored in qryld 732. However, in this example, the component value stored in qryld 732 must be unique for each source object, and may comprise only printable characters, qryld 732 is of a string type in this exemplary implementation; however, it may be of any other data type which is sufficient for implementing a primary key, such as, a long integer, a short integer, a GUID, and the like.

[0344] qryWhr 752 is utilized for storing a WHERE clause expression in this exemplary data model. qryWhr 752 is of a string type and should be of a sufficient size to store all the desired WHERE clause expressions, along with one or more token values representing tknCurly Brackets 526, tknltemCodeBegin 528, and/or tknltemCodeEnd 530. A component stored in qryWhr 752 is a string, which:

1. is optionally embedded in one or more of the following:

a. a token value representing tknCurlyBrackets 526,

b. a token value representing tknltemCodeBegin 528,

c. a token value representing tknltemCodeEnd 530, and

d. any combinations thereof, and

2. becomes a valid WHERE clause expression, as may be desired for MICROSOFT

ACCESS, or for ORACLE, or for both MICROSOFT ACCESS and ORACLE, after all token values, which represent tknCurlyBrackets 526, tknltemCodeBegin 528, and/or tknltemCodeEnd 530, and which are embedded in the component values that are stored in qryWhr 752, are processed.

[0345] qryGrp 512 is embedded in query 702, so as to enable queryBuilder to determine whether a desired query is an aggregate query or not.

[0346] qryUni 514 is embedded in query 702, so as to enable queryBuilder to determine whether a desired query is a UNION ALL query or not.

[0347] Query source 704 is a child entity of query 702, wherein query 702 has a one-to- many relationship 712 with query source 704. Query 702 also has another one-to-many relationship 714 with query source 704. The one-to-many relationship 714 is optional. Query 702 comprises following attributes:

1. srcQryld 734,

2. srcOrd 736,

3. srcld 754,

4. srcReuseld 738,

5. srcUseCnd 516,

6. srcJoinFId 756, 7. srcJoinToFId 758, and

8. srcJoinToSrc 760.

[0348] srcQryld 734 is an exemplary attribute which is utilized in query source 704 for enabling a one-to-many relationship 712. srcQryld 734 is a foreign key which is related to qryld 732 of query 702. In query source 704, srcQryld 734 is implemented as a string data type, and is of the same size as of qryld 732. srcQryld 734 and srcld 754 serve as a composite primary key in query source 704.

[0349] srcOrd 736 is an exemplary attribute which is utilized in query source 704 for maintaining a desired order among a plurality of component values that are stored in srcld 754. In query source 704, srcOrd 736 is implemented as a long integer data type; however, srcOrd 736 can be implemented as any other data type which is sufficient for maintaining an order among a plurality of component values that are stored in srcld 754. Such data types may include, but are not limited to, a short integer, a string, and a floating point.

[0350] srcld 754 is utilized for specifying the name of a table/view which is desired to be utilized for constructing a desired query. The component values stored in srcld 754 must be unique within one source object because srcld 754 is a part of the composite primary key of query source 704. src!d 754 may be represented by either: . a component value which represents a table/view name which exists in a database which is intended to execute a desired query, or

2. an arbitrary view name (which must comprise all printable characters in this

example), only if a data value represents srcReuseld 738.

[0351] srcReuseld 738 is an exemplary attribute which is utilized in query source 704 to enable a utilization of another source object in query source 704. srcReuseld 738 is a foreign key and may optionally comprise a value from qryld 732. For this example, srcReuseld 738 cannot comprise a data value which represents its parent qryld 732, because such a data value will cause an infinite recursive loop in this exemplary data model. The one-to-many relationship 714 is implemented by utilizing qryld 732 and srcReuseld 738.

[0352] srcUseCnd 516 is embedded in query source 704. If the processing of the token value comprised by srcUseCnd 516 determines that srcld 754 cannot be utilized for constructing a desired query, then the complete record, comprising the token value of srcUseCnd 516 and the data value of srcld 754, including all child records, will not be utilized for constructing a desired query. [0353] srcJoinFId 756, srcJoinToFId 758, and srcJoinToSrc 760 are utilized to specify information which is required to join two tables, two views or one table and one view.

srcJoinFId 756 is utilized to specify a field alias which belongs to a table/view specified by srcld 754 of the current record. srcJoinToFId 758 is utilized to specify a field alias which belongs to the other table/view which is to be joined with table/view specified by srcld 754 of the current record, and is specified by the component value representing srcJoinToSrc 760. In this exemplary embodiment, self joins are not implemented.

[0354] Query field 706 is a child entity of query source 704, wherein query source 704 has a one-to-many relationship 716 with query field 706. Query field 706 comprises the following attributes:

1. colQryld 740,

2. colSrcld 742,

3. colOrd 744,

4. colAla 762,

5. colXpr 764,

6. colUseCnd 518,

7. colGrpFun 766, and

8. colReuse 520.

[0355] colQryld 740 and colSrcId 742 are two exemplary attributes which are utilized in query field 706 for enabling the one-to-many relationship 716. colQryld 740 and colSrcId 742 are foreign keys which are related to srcQryld 734 and srcld 754 respectively. colQryld 740 and colSrcId 742 are implemented by utilizing a string data type and are of the same size as srcQryld 734 and srcld 754 respectively. colQryld 740, colSrcId 742, and colAla 762 serve as a composite primary key in query field 706.

[0356] colOrd 744 is an exemplary attribute which is utilized in query field 706 for maintaining a desired order among a plurality of those component values that are stored in colAla 762. In query field 706, colOrd 744 is implemented as a long integer data type;

however, colOrd 744 could have been implemented as any other data type which is sufficient for maintaining a desired order among a plurality of component values which are stored in colAla 762. Such data types may include, but are not limited to, a short integer, a string, and a floating point.

[0357] colAla 762 is utilized to specify a valid column/field alias for a desired query. colAla 762 is implemented as a string data type in this exemplary data model. A component value, which is stored in colAla 762, may also be embedded with %TknMth% which is a token value representing tknMonth 524. The component values stored in colAla 762 must be unique within one source object with reference to their parent component value, which is stored in srcld 754, because colAla 762 is a part of the composite primary key of query source 704.

[0358] colXpr 764 is utilized to specify a valid expression for a desired query. colXpr 764 is implemented as a string data type in this exemplary data model. A component value, which Is stored in colAla 762, may also be embedded with:

1. one or more token values representing tknMonth 524, and/or

2. one or more "!" (exclamation mark without quotes) representing tknAlias 522.

[0359] colUseCnd 518 is embedded in query field 706. If the processing of the token value comprised by colUseCnd 518 determines that colAla 762 cannot be utilized for constructing the desired query, the entire record, comprising the token value of colUseCnd 518 and component values of colAla 762, will not be utilized for constructing a desired query.

[0360] colGrpFun 766 is utilized for specifying a SUM function for columns/fields which are desired to be summed in a desired query which is constructed as an aggregate query. In this exemplary embodiment, if colGrpFun 766 is represented by "SUM" (without quotes), then the SUM function is applied to the component value stored in colXpr 764. Otherwise, if colGrpFun 766 is represented by "Group" (without quotes), then colAla 762 is utilized in a GROUP BY clause, otherwise the component value stored in colXpr 764 is treated as an expression and is not included in the GROUP BY clause. In this exemplary embodiment, the utilization of only the SUM function is illustrated; however, colGrpFun 766 can be utilized for implementing any other function, such as, AVG, MAX, MIN, and the like.

[0361] colReuse 520 is embedded in query field 706, and is utilized to specify those records of query field 706 which are desired to be replicated.

[0362] Fig. 7C illustrates an exemplary implementation of the exemplary data model 164, illustrated in Fig. 7B, as an exemplary source object repository 168. Query 702 is implemented as a tbIQry 782, which is a MICROSOFT ACCESS database table. Query source 704 is implemented as a tbIQrySrc 784, which is a MICROSOFT ACCESS database table. Query field 706 is implemented as a tbIQryFId 786, which is a MICROSOFT ACCESS database table.

[0363] Figs. 8A to 8P illustrate an exemplary flowchart of an exemplary software component constructor 170 which is implemented as a function and is called queryBuilder. queryBuilder is utilized for constructing a desired query by utilizing a source object 166, which is stored in tbIQry 782, tbIQrySrc 784, and tbIQryFId 786, which are the data tokens illustrated in Fig. 5A, and the parameters illustrated in Fig. 6. The exemplary flowchart may be implemented in any computer programming language. The variable names and the programming conventions utilized in the exemplary flowchart are not dependent on any specific computer programming language. However, the implementation of this exemplary flowchart may require a programming language specific interpretation of one or more operations, illustrated in the exemplary flowchart. For example, a concatenation of two or more string values in the exemplary flowchart is represented by a plus sign, whereas this same operation is represented by an ampersand sign in some programming languages. Moreover, all variable names and function names utilized in the exemplary flowchart are exemplary and can be changed as may be desired and/or required for any particular implementation.

[0364] In the exemplary flowchart, the UNION ALL operator is implemented for sub queries only.

[0365] In the exemplary flowchart, arguments argComp, argTrue and argFalse are utilized symbolically. However, the values comprised by these arguments will be utilized in each operation, wherever any of these arguments are utilized.

[0366] In the exemplary flowchart, it is implied that whenever tknMonth 524 is replaced in an operation, the complete representation of tknMonth 524, starting from the first % (percent sign) to the last % (percent sign), is replaced. For this exemplary flowchart, it is assumed that only one token value representing tknMonth 524 is embedded in one database field.

[0367] In the exemplary flowchart, a variable is considered empty if the variable:

1. is empty, or

2. comprises a NULL value, or

3. comprises an empty value according to its data type, for example, an empty string, a zero, and a False.

[0368] In the exemplary flowchart, all variables, except for varCalCnt and varMthAry, are defined at the module level, and are created again on any recursive call to the function queryBuilder, with the previous variables retaining their respective values. However, the variables varCalCnt and varMthAry are not initialized on a recursive call to the function queryBuilder. All parameters, defined in Fig. 6, are defined at a global level, and are not initialized on any recursive call. [0369] In the exemplary flowchart, double quotes are utilized for identifying a string value. The double quotes are never a part of the string in the exemplary flowchart. However, a single quote, whenever utilized, is a part of a string value.

[0370] The exemplary flowchart does not include any error and/or exception handling; it is assumed that all the component values and token values are provided correctly, and are within the required ranges.

[0371] The exemplary flowchart is self-explanatory. However, for clarity, some operations have been described in greater detail.

[0372] In the exemplary flowchart illustrated in Figs. 8A to 8X, the field names of tbIQry 782, tbIQrySrc 784, and tbIQryFId 786 are utilized without their respective numerals. The field names of the aforementioned tables, which represent attributes of the exemplary data model, are listed below:

1. qryld 732,

2. qryWhr 752,

3. qryGrp 512,

4. qryUni 514,

5. srcQryld 734,

6. srcOrd 736,

7. srcld 754,

8. srcReuseld 738,

9. srcUseCnd 516,

10. srcJoinFId 756,

1 . srcJoinToFId 758,

12. srcJoinToSrc 760,

13. colQryld 740,

14. colSrcld 742,

15. colOrd 744,

16. C0lAla 762,

17. colXpr 764,

18. colUseCnd 518,

19. colGrpFun 766, and

20. colReuse 520. [0373] In addition to the above-mentioned field names, the following data tokens, parameters, and table names are also utilized without their respective numerals in the exemplary flowchart illustrated in Fig. 8A to 8X:

1. prmQryld 612,

2. prmMthCnt 614,

3. prmOraQry 618,

4. prmLftJoi 620,

5. tblQry 782,

6. tbIQrySrc 784,

7. tbIQryFId 786,

8. tknMonth 524,

9. prmBegMth 616, and

10. prmUseCnd 622,

[0374] In Fig. 8A, at terminal 810a, the function queryBuilder starts. queryBuilder receives a parameter for prmQryld 612, which is utilized to identify a desired source object from tbIQry 782.

[0375] At decision box 810b, it is checked whether this is the first call to queryBuilder or not. This check is required for a one-time initialization of the global variables, varCalCnt and varMthAry, which are initialized at operation 810c and operation 81 Od respectively. If this is the first call to queryBuilder, then the flow continues to operation 810c. Otherwise, the flow continues to operation 810e.

[0376] At operation 81 Oe, an object varQryRcd is initialized. The object varQryRcd is an exemplary ADO Recordset Object, and comprises information about a Recordset, which is opened by utilizing the object varQryRcd.

[0377] At operation 810f, an object varSrcRcd is initialized. The object varSrcRcd is an exemplary ADO Recordset Object, and comprises information about a Recordset, which is opened by utilizing the object varSrcRcd.

[0378] At operation 810g, an object varFldRcd is initialized. The object varFldRcd is an exemplary ADO Recordset Object, and comprises information about a Recordset, which is opened by utilizing the object varFldRcd. [0379] At operation 810h, an array variable varTblAry is initialized. varTblAry is a two dimensional array that is utilized for storing component values in srcld 754 along with a table/view alias, which is generated, as a result of processing tknAlias 522, for srcld 754.

[0380] In Fig. 8B, operations 811 p and 811q are called only once for a query; these operations are not called for sub-queries.

[0381] At operation 811 p, varAlaCnt is initialized to zero. varAlaCnt is utilized for calculating an alias for tknAlias 522.

[0382] At operation 811q, all parameters illustrated in Fig. 6 are resolved. The parameters may either be resolved by a direct input of a user, or be retrieved from a computer readable recording medium.

[0383] In Fig. 8C, at operation 812b, the object varQryRcd is opened, wherein the object varQryRcd comprises all fields of tbIQry 782, wherein the data value of qryld 732 is equal to the parameter value 162 of prmQryld 612. Since qryld 732 is the primary key, the object varQryRcd will comprise maximum one record.

[0384] At operation 812c, the object varSrcRcd is opened, wherein the object varSrcRcd comprises all fields of tbIQrySrc 784, wherein the data value of srcQryld 734 is equal to the data value of qryld 732, and the order of the Recordset comprised by the object varSrcRcd is on the data values of srcOrd 736.

[0385] At operation 812f, the varSrcAvl is assigned a result of the processed token value of srcUseCnd 516. The processing of the token value of srcUseCnd 516 is done in an exemplary function called CheckAvailability, which is illustrated in detail in Fig. 8Q. If the function CheckAvailability returns True, it implies that the current record pointed by the object varSrcRcd will be utilized by queryBuilder. If, on the other hand, the function CheckAvailability returns False, it implies that the current record pointed by the object varSrcRcd will not be utilized by queryBuilder.

[0386] At operation 8121, tknAlias 522 is processed. tknAlias 522 is processed by an exemplary function NewAlias(), which is illustrated in detail in Fig. 8R. The alias generated by a function NewAlias() is then stored in a variable varCurAla.

[0387] In Fig. 8D, at operation 813c, queryBuilder is called recursively for constructing a sub-query, wherein the sub-query is identified by a data value of srcReuseld 738. The resultant sub-query is stored in a variable varSubQry. [0388] At operation 813i, the object varFldRcd is opened, wherein the object varFId Red comprises all fields of tbIQryFId 786, wherein the data value of colQryld 740 is equal to the data value of srcQryld 734, the data value of colSrcId 742 is equal to the data value of srcld 754, and the order of the Recordset represented by the object varFldRcd is on the data values of colOrd 744.

[0389] At operation 813m, varFldAvl is assigned a result, which is an example of token result 156, of the processed token value of coiUseCnd 518. The processing of the token value of coiUseCnd 518 is done in the exemplary function CheckAvailability, which is illustrated in detail in Fig. 8Q. If the function CheckAvailability returns True, it implies that the current record pointed by the object varFldRcd will be utilized by queryBuilder. If, on the other hand, the function CheckAvailability returns False, it implies that the current record pointed by the object varFldRcd will not be utilized by queryBuilder.

[0390] Fig. 8Q illustrates an exemplary flowchart of an exemplary processing of two data tokens, srcUseCnd 516 and coiUseCnd 518, wherein the processing of srcUseCnd 516 and coiUseCnd 518 is implemented by utilizing the exemplary function CheckAvailability. Since the processing logic of both data tokens, srcUseCnd 516 and coiUseCnd 518, is the same, the processing of both data tokens is implemented as one function.

[0391] At operation 826a, the function CheckAvailability starts and receives a parameter prmCndTkn which comprises a parameter which will be either a token value representing srcUseCnd 516, or a token value representing coiUseCnd 518, depending on the location from where the function CheckAvailability is called.

[0392] At operation 826d, the parameter value 162 of prmUseCnd 622, which comprises either a list of comma-separated string values, or a single string value, is stored as an array in an array variable varCndPrm. The following are a few examples illustrating the storage of contents of prmUseCnd 622 as an array in varCndPrm:

1. If prmUseCnd 622 is empty, then varCndPrm will comprise no array item.

2. If prmUseCnd 622 comprises only one string value, then varCndPrm will comprise one array item.

3. If prmUseCnd 622 comprises 10 comma-separated string values, then varCndPrm will comprise 10 array items, wherein each array item will comprise a string value.

[0393] Fig. 8R illustrates an exemplary flowchart of an exemplary processing of the function NewAlias(), which is utilized for an exemplary processing of tknAlias 522. Each time the function NewAliasQ is called, it returns a new alias comprising one or more alphabets. [0394] At operation 827a, the function NewAlias() starts.

[0395] At operation 827e, MOD represents modulo operation, which finds the remainder of a division of the value of a variable varWrkCnt by 26.

[0396] At operation 827f, INT represents an integer function, which returns only the integer part of a number without rounding the number.

[0397] At operation 827i, CHR represents a function, which returns an ASCII character which is represented by the number that is passed to CHR as a parameter.

[0398] At operation 827k, the function NewAlias() returns the newly calculated alias.

[0411] Fig. 9E illustrates an exemplary segment of tbIQry 782 (represented as 782e because it illustrates a specific exemplary segment of tbIQry 782) which shows an exemplary source object which is identifiable by qryPur (a data value which represents qryld 732), hereinafter called exemplary source object qryPur, and is represented in record 902. The exemplary source object qryPur is utilized in another source object, which is identifiable by qryUnion (a data value which represents qryld 732), hereinafter called the exemplary source object qryUnion, illustrated in Fig. 9G. However, queryBuilder can construct a desired query by utilizing only the exemplary source object qryPur.

[0412] An exemplary segment of tbIQrySrc 784 (represented as 784e because it illustrates a specific exemplary segment of tbIQrySrc 784) comprises one record 902a which is related to record 902. Record 902a illustrates a table which is to be utilized in a desired query that is to be constructed by utilizing the exemplary source object qryPur and/or any other query, which queryBuilder constructs by utilizing a source object which utilizes the exemplary source object qryPur.

[0413] In record 902a, srcUseCnd 516 is represented by an exemplary token value comprising a list of comma separated string comprising two string values: TknPur and TknZon. Utilization of srcUseCnd 516 implies that during the construction of a desired query which utilizes the exemplary source object qryPur, record 902a will be utilized only if the parameter value 162 of prmUseCnd 622 comprises at least one of the string values: TknPur and TknZon. In a case where record 902a is not utilized, the records illustrated in an exemplary segment of tbIQryFId 786 (represented as 786e because it illustrates a specific exemplary segment of tbIQryFId 786) will also not be utilized.

13. A few benefits and commercial applications of the invention

[0470] The benefits and advantages of this invention are numerous and overwhelming, and can readily be achieved in most computer programs. This invention also has huge commercial potential. Any commercial application based on this invention will have power and functionality well beyond what can be achieved in the prior art. Even existing commercial products and applications, like computer programs, can be made extremely powerful, flexible, dynamic, feature rich and cost effective by utilizing this invention.

Utilization of this invention will open new horizons in software development and take it to a new programming paradigm which will be beneficial for software developers as well as software users.

[0471] It will be apparent to anyone familiar with the art that this invention can readily be applied/utilized in almost every aspect of software development, particularly in almost any computer program, existing or new.

[0472] This invention will enable development of software which can easily develop software components on a user's demand, as and when required.

[0473] This invention will greatly simplify and streamline the development of software. Most of the complexities currently faced by software developers will be wiped out. This will lead to another vital advantage: extensive training of human beings for software development will no longer be required. As a result, productivity of human beings will be greatly enhanced, and result in substantial cost savings in terms of finance and time.

[0474] The streamlining and simplification of software development achieved under this invention will particularly reduce the time presently required for software development. The time required to develop a software program under this invention will only be a very small fraction of the time required in the prior art. For example:

1. By utilizing this invention, development of database queries can be made so simple and efficient that it can save hundreds of thousands of man hours for even a medium-size computer program.

2. The innovative source object repository of the invention can make software

development so simple and easy that even a novice software developer will be able to produce such outstanding results in only a few minutes that, in the prior art, a highly skilled professional software developer could not produce in months.

[0475] By utilizing this invention, creating and managing database queries will become extremely efficient and cost effective. Hundreds of thousands of man hours of query writing, query testing, and query debugging can be saved for even one computer program. This will make creating, managing, maintaining, modifying, as well as providing quality assurance of database queries substantially easier than in the prior art. The extraordinary ease in query building will particularly benefit software developers.

[0476] The inventive concepts of a source object repository, a software component constructor, reusability, a data token, and a parameter will make it possible to substantially reduce the quantum of queries which, in the prior art, may span hundreds of thousands of query lines. Software development in general, and business intelligence in particular, will greatly benefit from such reduction. A few possibilities under this invention are discussed below:

1. Database queries: This invention can substantially improve creating, testing, and debugging database queries in any database management system and/or any computer program which utilizes database queries.

2. Reporting: Reporting is an important segment of any computer program. Application of this invention to a reporting computer program will enable a computer to generate millions of report layouts, along with respective database queries, from a single source object.

3. Data entry forms: This invention will allow development of data entry forms which can be customized either at runtime and/or according to a user's requirements. It will also become possible to develop business applications which can be utilized and deployed in one or more different industries, across one or more different regions/countries having different laws and environments.

4. Business processing rules: Business processing rules are one of the most significant parts of a computer program. The business processing rules vary greatly from one industry to another, and also from one country to another. For this reason, many computer programs which rely heavily on business processing rules, such as payroll processing, tax calculation, and the like, can only be developed for specific industries and/or regions. This invention makes it possible to develop computer programs that are utilizable in cross industry and in cross region.

5. Software configuration: One of the most time-consuming and resource-hungry

phases in software deployment is software configuration according to a user's requirements. Even small business applications take months to deploy. The present invention enables development of computer programs that can be configured and deployed in a fraction of the time required in the prior art.

6. The invention can similarly be applied to a user management system, an error management system, a help system, a user interface, a software wizard, a gaming engine, etc.

[0477] This invention can be utilized in almost every type of software program and application. Therefore, it is next to impossible to list all possible applications of the present invention. However, some exemplary commercial applications and usages are mentioned below:

1. Business intelligence based computer programs utilize many software components, such as, a database query, a report layout, a user interface, a user management system, and the like. This invention can be applied to all these components. However, by applying this invention only to database queries and report layouts, the business intelligence computer programs can be made hundreds of times more powerful, intelligent, and economical. The current invention will open up new possibilities in data analysis and reporting which are impossible to achieve, or even conceive, in the prior art.

2. This invention can also be utilized to enhance the productivity and functionality of existing business intelligence computer programs such as CRYSTAL REPORTS, COGNOS, and the like, to a level that is unachievable in the prior art.

3. Given below are a few software application categories which can benefit from the present invention in terms of power, flexibility, dynamism, and cost effectiveness: a. Business intelligence.

b. Database management system.

d. ERP (Enterprise Resource Planning) software.

e. SCM (Supply Chain Management) software.

f. GIS (Geographical Information System) software.

g. DAM (Digital Asset Management) software.

h. MRP (Material Requirements Planning) software.

i. SFA (Sales Force Automation) software.

j. CAE (Computer Aided Engineering) software,

k. CAD (Computer Aided Design) software.

I. Hotel management software. m. Human resource management software.

n. Banking software.

o. Web based applications.

p. Manufacturing control systems.

q. Process control systems.

[0478] This invention makes it possible for a developed computer program, and its related resources, to be utilized, as many times as may be desired, in another computer program. Anyone familiar with the art will immediately capitalize on this advantage. For example, if a query building engine (which is a software component constructor) is developed on the basis of this invention, it can be utilized in any other computer program. By only porting the query building engine to any other platform, all the queries written for the query building engine can readily be utilized on other platforms.

[0479] The innovative software component constructor, which is developed on the basis of this invention, can easily be utilized for constructing billions and trillions of different software components, even from a single source object. This gives software development new potential which is unthinkable in the prior art.

[0480] Under this invention, the benefits of reusability and multiplicity of instantly available software components will be readily available for almost all software components, such as, reports, data entry forms, business processing rules, error management systems, knowledge base systems, web portals, computer games, and the like.

[0481] This invention makes it possible to develop software components in small pieces and test each piece individually and independently. This possibility enables a software developer to manage a computer in a way that each piece of a software component is developed and tested independently, and then all the pieces of the software component are combined together to work as a single software component. This power is achieved by utilizing the innovative source object repository, data tokens and reusability of one or more component values.

[0482] This invention enables creation of software factories which work as real factories thus making software industrialization a reality.

[0483] In the prior art, most computer programs are developed in a way that they have to be maintained at a huge cost in terms of time, human effort and financial resources. However, this invention makes maintenance of software so convenient and easy that is unimaginable in the prior art. Moreover, this invention teaches a software developer to develop software in such a manner that maintaining developed software is hassle-free and no more than a minor routine. For example, if a conventionally developed computer program utilizes a couple of hundred queries based on one database table, adding a new column in each database query may require tens of thousands of man hours. But, in a similar computer program which is developed on the basis of this invention, such a change will require only a few minutes.

[0484] In the prior art, the ability to develop software which is platform independent has been an ongoing challenge which has not been met effectively. This invention enables this ability to such a level that is unheard of in the prior art. By utilizing this invention, it is possible to develop a software component constructor which can construct software components for a plurality of platforms. For example, a reporting engine, which is a software component constructor, can be developed under this invention that can construct report layouts for CRYSTAL REPORTS, MICROSOFT ACCESS, and many other reporting programs from a single source object.

[0485] Software developed by utilizing this invention utilizes the available computing resources efficiently. Storage requirements for a computer program developed on the basis of this invention is substantially smaller than the storage requirements for a similar computer program developed according to the conventions used in the prior art. Moreover, utilization of network bandwidth is also optimized because of the much reduced size of the computer program developed under this invention. Hence, it is extremely efficient to deploy computer programs developed under this invention, in networked and/or web based environments, such as cloud computing, client server architecture, and the like.

[0486] Software which is developed on the basis of this invention is also inherently resource efficient in terms of software support to a user. Because of the inherent architecture of such software, it is possible to upgrade and maintain such software very efficiently and at an extremely low cost. The resources required to support computer programs developed by utilizing this invention are only a fraction of the resources required to support similar programs developed in the prior art.

[0487] Utilization of this invention for software development will enable optimization for minimizing the software development resources and maximizing the software efficiency, flexibility and/or output, and will enable a user to have: (1 ) precise control, (2) dynamic change, and/or (3) any combinations thereof, in: (i) the behavior of software, (ii) the outcome of software, (iii) the reusability of program data, (iv) the ease of software development, and/or (v) any combinations thereof; and all of the above, especially: (a) at runtime and/or (b) by utilization of one or more control parameters. [0488] Software developed on the basis of this invention also gives unmatched runtime power, flexibility, and dynamism to a user. Utilization of a source object repository, a data token, and a parameter enables developed software to also work as an intelligent component constructor which can instantly construct a software component on the basis of a user's desire at runtime; indeed, the user may utilize the developed software according to the ever-changing and growing business requirements. For example, it is possible, under this invention, to develop a reporting system which can produce almost any conceivable data combination instantly on a user's demand. Such possibilities are inconceivable in the prior art.

[0489] By utilizing this invention, it is possible to create computer programs which can cater to almost any future requirement, only by either changing one or more parameters, or by adding new component values, data tokens and/or parameters, as may be pertinent for any new/future requirement.

[0490] Since any software, developed on the basis of this invention, is very easy to maintain, it is possible to extend the life cycle of developed software by many years.

[0491] In a nutshell, this invention is a unique and breakthrough development. It will provide total flexibility and dynamism to a software developer and user in software development, especially at runtime. Moreover, this invention will cater to the complex and massive demands on software, precipitated by the exponential growth of computing power, accounting for both the current and future requirements. Indeed, the invention is unique in its nature and scope, and no similar prior art exists in this regard.
