A JDBC database server is required to use persistent reliable messaging with WSO2 SOA Enablement Server for Java™ . This guide describes the JDBC integration of WSO2 SOA Enablement Server for Java™ with the most common database servers.

	Note
	Database configuration is performed after installing WSO2 SOA Enablement Server for Java™ .

WSO2 SOA Enablement Server for Java™ has two components for accessing databases: the database core and database persistence components. These are found in the WASP_HOME/lib/db_interface.jar archive.

The database core component provides a level of abstraction to access databases via the JDBC API. The means of access can vary from database to database. This component allows you to share connections to any database via the connection pool.

The database persistence component uses the database core component and enables developers to store persistent objects using a higher level of abstraction.
