Object-oriented database systems

Abstract

The object model which is based on the abstract data type concept, provides a natural and more powerful modeling capability. This modeling power, coupled with efficiency of implementation, makes object-oriented database systems suitable for complex applications, such as engineering design applications. The author concentrates on: differences between object-oriented databases and object-oriented programming languages and differences between object-oriented databases and classical (relational) databases. The author argues the need for supporting schema evolution and object versions.<>
