# Configuring Data Sources

The Data Source component requires no configuration—you simply place it on the page.

When you open the Data Sources component, you can see all of the data sources that have been configured for your application, as shown in this example:

Each data source definition consists of:

- The name of the data source.
- The version of the MDEX Engine they are using (ENE_QUERY for MDEX Engine Version 6).

By clicking a data source's icon (highlighted below), you can test the data source's connection. The icon changes and mousing over it provides a confirmation message.

To reload updated configuration based on edits made on disk, you click the Reload data sources button. (For details on making these edits, see the Discovery Framework Extension Guide.)

Note: Configuration of data sources themselves takes place offline.
