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 • An OODBMS 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.
- 5. Comparisons Of OODBMSs To RDBMSs
- 6. Advantages • Composite Objects and Relationships • Class Hierarchy
- 7. Advantages • Circumventing the Need for a Query Language • No Impedance Mismatch
- 8. Advantages • No Primary Key • One Data Model
- 9. Disadvantages • Schema Changes • Language Dependence • Lack of Ad-Hoc Queries
- 10. List Of Object Oriented Database Management Systems • Proprietary ▫ Object Store ▫ O2 ▫ Gemstone ▫ Versant ▫ Ontos ▫ DB/Explorer ODBMS ▫ Ontos ▫ Poet ▫ Objectivity/DB ▫ EyeDB • Open ▫ Ozone ▫ Zope ▫ FramerD
- 11. OODBS Features
- 12. Mandatory features of object-oriented systems • Support for complex objects • Object identity • Encapsulation • Support for types or classes ▫ Type ▫ Classes • Class or type hierarchies • Overriding, Overloading and Late Binding • Computational Completeness
- 13. Mandatory features of database system • Persistence • Secondary Storage Management • Concurrency • Recovery • Ad hoc query facility
- 14. Conclusion • There are many gains from using an OODBMS while developing an application using an OO programming language. • Saves development times.
