A JDBC control makes it easy to access a relational database from your application. Using the JDBC control, you can issue SQL commands to the database. The JDBC control automatically performs the translation from database queries to Java objects, so that you can easily access query results.
A JDBC control can operate on any database for which an appropriate Java Database Connectivity (JDBC) driver is available or which has a data source configured in WebLogic Server. When you add a new JDBC control to your application, you specify a data source for that control. The data source indicates which database the control is bound to.
