Managing data sources
Data source is a location of data for your application.
In CLion, you can define the following data sources:
Database data source: operational databases that contain data (see Connecting to a database).
Data Definition Language (DDL) files: SQL files that contain data definition language statements (see Add a DDL data source).

To ensure that the connection to the data source is successful, click Test Connection.
Click OK.
Create a DDL data source
Open the Database tool window ().
Click the Data Source Properties icon (

Group data sources
If you have a number of different databases, you can group their data sources in the Database tool window (). To group data sources, select the necessary data source, press F6, or select Move to Group from the context menu.
The following options are available for data source groups in the Move to Group menu:
