### Setting Up Database Access

Make sure that the JDBC drivers that you want to use to create database connections are installed on all servers on which you want to deploy the data source. In the Application Server, you configure database connectivity by adding JDBC data sources to the domain. A data source is a Java EE 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 JNDI tree or in the local application context and then reserve a database connection with the `getConnection` method. Data sources and their connection pools provide connection management processes that help keep your system running.
