Abstract

A database system having a logical database, a knowledge base and a client information module is provided. The knowledge base contains knowledge regarding semantic and syntactic constraints of data relationships of data contained in the logical database. The client information module is coupled between the logical database and the knowledge base, the client information module providing an interface between a user of the database system and allowing use of the logical database according to the knowledge contained in the knowledge base. Since the knowledge necessary to maintain consistency in the database system is already contained in the knowledge base, a user can use the database system, which may contain a plurality of different relational databases, without extensive expertise in the particular databases.
