Explanation:
Applications look up the data source on the JNDI tree or in the local application context (B) and then reserve a database connection with the getConnection (E) method. Data sources and their connection pools provide connection management processes that help keep your system running and performant.
B: JNDI Name - Enter the JNDI path to where this JDBC data source will be bound. Applications look up the data source on the JNDI tree by this name when reserving a connection.
Note: If you've done any work with JDBC DataSources in a Web application, you already understand the basic process: create an initial JNDI (Java Naming and Directory Interface) context, then use the context to perform a "lookup" to retrieve your DataSource.
