# JDBC Data Source Factory --> Configuration

Tasks Related Topics Attributes

## Overview

A JDBC data source factory is an instance of a JDBC data source resource bound to the WebLogic Server JNDI tree as a resource factory. An application-scoped JDBC connection pool relies on a JDBC data source factory to provide default connection pool values. You must create a data source factory before you deploy an enterprise application that includes an application-scoped connection pool. The `weblogic-application.xml` supplemental deployment descriptor for the application must reference the data source factory by the factory name that you specify in the Administration Console.

Properties that you specify for a data source factory are used as default values for application-scoped connection pools that reference the factory. You can override the default values in the `weblogic-application.xml` supplemental deployment descriptor.
