A method and object-oriented architecture for interfacing a user to a relational database system The contour of the interface is defined by a profile object and a task object. The profile object, in response to user selection, defines one of multiple role objects with associated user proficiency and system behavioral characteristics. The task object responds to parameters derived from the profile object to generating a query for the relational database system. In one form, the task object includes one or more functional objects suitable to query the database. Representative functional objects are the domain object (used to formulate problem oriented queries), the analysis object (used to analyze the data extracted from the database), the report object (used to generate a user response format), and the link object (used to relate the components within the task object). The interface according to the invention matches the abilities of the user to the resources of the database system, manipulates problem oriented high-level queries, and provides an object oriented architecture readily amenable to object refinement.
