Advance Database Management Systems -Object Oriented Principles In Database
This document provides an overview of object-oriented database management systems (OODBMS), which combine object-oriented programming principles with database management. It discusses how OODBMSs support encapsulation, polymorphism, inheritance and ACID properties while allowing for complex objects, relationships, and queries of large amounts of data. The document also lists advantages and disadvantages of OODBMSs compared to relational database systems and examples of both proprietary and open-source OODBMSs.

- 3. INTRODUCTION • AnOODBMS is the result of combining object oriented programming principles with database management principles. • Object oriented programming concepts such as encapsulation, polymorphism and inheritance are enforced as well as database management concepts such as the ACID properties which lead to system integrity. • Support for an ad hoc query language and secondary storage management systems which allow for managing very large amounts of data.

- 14. Conclusion • Thereare many gains from using an OODBMS while developing an application using an OO programming language. • Saves development times.
