OODBMS Basics

Summary

In this final chapter of Part I we looked at the basics and terminology of object databases. In doing so we contrasted db4o with databases that follow the ODMG standard, showing that db4o adheres much more closely to the object model familiar to .NET and Java programmers. We saw that object identity is a fundamental OODBMS concept that underpins the way that relationships between entities are represented, and we learned how object databases deal with key database capabilities such as querying and concurrency.

Part II builds on the concepts that have been introduced so far, and takes a detailed “hands-on” approach to the use of db4o, from installing and getting started all the way through to taking advantage of its advanced features.
