Object-Oriented Database Management Systems

Course Description

The object-oriented paradigm has given rise to a new generation of database systems. Object-oriented database management systems (OODBMS) combine the strength of the object-oriented paradigm with the speed gained from the close integration of the storage and execution model. The course explains what an OODBMS is, how it differs from relational database technology, and how it improves object-oriented application software. Major commercial and research OODBMS's are illustrated and a case study explains how an application can take advantage of this new technology.

Course Objective

The objective of this course is to prepare attendees to effectively use object-oriented database technology. Upon completion of this course attendees will be able to:

Explain the benefits of object-oriented databases. 
Know the major features of an OODBMS. 
Know how to integrate an OODBMS with an application. 

Audience

This course is primarily directed toward designers and programmers. In addition, analysts and testers would benefit from this material.

 Prerequisites

Object-Oriented Analysis and Design Concepts or its equivalent.

Course Duration

Object-Oriented Database Management Systems is a two day course.
