INTRODUCTION

What is oodbms

An oodbms is the result of combining object oriented programming principle with database management principle.

OVERVIEW OF OODBMS

Oodbms provided the feature like complex object, object identity, encapsulation types and overhidding, overloading

WHAT IS DIFFERENCE BETWEEN OODBMS AND RDBMS

FEATURE OF OODBMS Feature of oodbms from genaral

database: able to handle large database controlled concurrency Feature of oodbms in object

oriented database: construction of complex object feature of classes and types

MAJOR CLASSES IN THIS SYSTEM

user persistable remote object owner sharable document remote object factor client view client control client state

OPEN SOURCE SOFTWARE IN OODBMS EYEDB EYESB 2.8.7 EYEDB IN LINUX + MAGZINE VERSANT B40 XRX

KEY FEATURE OF EYEDB

Genericity & orthogonality of object model efficiency scalability

OZON JAVA BASED OODBMS Db40 E4graph coldstore

SERVICES PROVIDED BY OODBMS Extensibility expressive power support for schema evolution improved performance reusability

APPLICATION before we begin we should aknowledge reality there are situtation in which an rdbms just fine. but after a time superior database application is oodbms are found

SCOPE AND LIMITATION

Advantages: composite object and relationship. no impendence mismatch no primary keyDisadvantages: schema change language dependence

CONCLUSION oodbms is a dbms with an underlaying object oriented data model oodbms has three model
