## JDBC

Java Database Connectivity (JDBC) technology provides connectivity to relational databases. In the JDBC area of the Administration Console, you can configure and monitor JDBC components, including connection pools and data sources.

A JDBC resource (data source) provides applications with a means of connecting to a database. Typically, the administrator creates a JDBC resource for each database accessed by the applications deployed in a domain. (However, more than one JDBC resource can be created for a database.)

A JDBC connection pool contains a group of JDBC connections that are created when the connection pool is registered. Connection pools use a JDBC driver to create physical database connections. Your application borrows a connection from the pool, uses it, then returns it to the pool by closing it. To create a JDBC resource, specify the associated connection pool. Multiple JDBC resources can specify a single connection pool.
