JavaTM DataBase Connectivity (JDBCTM) technology provides connectivity to relational databases. In the Enterprise Server, you configure database connectivity by adding JDBC resources (data sources) to the domain. A data source is a Java Platform, Enterprise Edition (Java EE platform) standard method of configuring connectivity to a database. Each data source contains a pool of database connections. Applications look up the data source on the Java Naming and Directory InterfaceTM (J.N.D.I.)
