# Create Data Source Dialog Box

This dialog box enables you to create a data source (JDBC resource) which provides applications with a means of connecting to a database. To connect to a database, the JNDI name of the data source is used to locate the associated database. Typically, the administrator creates a data source for each database accessed by the applications deployed in a domain. (However, more than one data source can be created for a database.)

To create a data source to use in your application, you need to supply the following:

Element | Description
--- | ---
JNDI Name | The JNDI name is the unique name for the data source. The JNDI name of the data source must also be registered on the target server. Note: Because the data source is a JDBC resource, the JNDI name is expected in the java:comp/env/jdbc subcontext. For example, for a database name MyDatabase, specify jdbc/MyDatabase as the JNDI name.
Database Connection | Choose the database connection to your database from the drop-down menu. The data source refers to a specific database connection. The drop-down menu contains the database connections listed under the Databases node in the Services window. Choose New Database Connection to create a new database connection.

When you create a new data source for your application, the data source description is added to `glassfish-resources.xml` under the Server Resources node of your project in the Projects window. If you are deploying to the GlassFish server, the data source is registered with the server upon deployment.
