The purpose of this manual is to introduce and describe the eZ Publish Extension for Oracle® Database (also known as the "ezoracle" extension or "database extension") version 1.8, which makes it possible to use Oracle as a database server for eZ Publish 4.0. The sections contained within this manual will help you to understand the following issues:

• The purpose of the "ezdb" library
• When the database extension is needed and when it isn't
• How to create a new eZ Publish site running on an Oracle database
• How to migrate an existing eZ Publish site from MySQL to Oracle

Important note

People previously unfamiliar with Oracle should read the "Oracle specific notes" section first.
