OBJECT-ORIENTED APPROACH TO DATABASE SYSTEM IMPLEMENTATION.

Abstract

Object-oriented programming is examined as an implementation technique for database systems. The object-oriented approach encapsulates the representations of database entities and relationships with the procedures that manipulate them. A generic procedure model of database implementation techniques is presented and discussed. Several current database system implementation techniques are illustrated as examples of this model, followed by a critical analysis of our implementation technique based on the use of objects. It is demonstrated that the object-oriented approach has advantages of data independence, run-time efficiency due to eliminating access to system descriptors,and support for low-level views.
