# Data Sources

The Data Sources component allows you to view configured data sources and test the connection to them. In addition, you can reload updated configuration based on edits you have made on disk.

Note: This component appears in the Liferay Control Panel and is not accessible from the Add Component menu.

Each Discovery Framework component that needs to query the MDEX Engine is tied to one particular data source. Changing any individual component's data source is done in that component's edit controls.

Note: For general information about Discovery Framework data sources, see the Discovery Framework Installation Guide. For information about data source configuration, security, and state management, see the Discovery Framework Extension Guide.
