Implementing NRDR Using OO Database Management System (OODBMS)

Abstract

Motives for using a database management system (DBMS) to build a knowledge base system (KBS), include KBS’s lack of ability to manage large sets of rules, to control concurrent access and to manage multiple knowledge bases simultaneously. In work, we build a KBS using a database management system DBMS for its schema evolution ability. We use this ability of an Object Oriented DBMS (OODBMS) to manage the consistency of an incrementally built knowledge base (KB).

The significance of this work is two folds: first, it provides an efficient mechanism maintaining consistency of an evolving classification hierarchy, using built-in schema evolution features of an OODBMS. Second, it enhances the interface of an OODBMS, to allow intelligent classification queries over stored objects.
