Abstract

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.

Claims

1. An object oriented user interface for a relational database system, comprising:

a profile object having role objects, including user proficiency and system behavioral characteristics, which define roles for a user;

a task object, including a domain object for interfacing a problem oriented user query to the relational database system, which defines a data base search query in response to a role object from the profile object; and

means for searching the relational data base system according to the query defined in the task object.

2. The interface recited in claim 1, further including means for a user to select a role object from the role objects of the profile object.

3. The interface recited in claim 2, wherein the task object further includes a link object, an analysis object and a report object.

4. A method for interfacing a user to a relational data base system, comprising the steps of:

creating a profile object having role objects, including user proficiency and system behavioral characteristics, which define roles for the user;

creating a task object, including a domain object for interfacing a problem oriented user query to the relational data base system, which defines a data base search query in response to a role object from the profile object; and

searching the relational data base system according to the query defined in the task object.

5. The method recited in claim 4, further including the step of selecting a role object from the role objects of the profile object.
