In the Database tool window ( ), click the Data Source Properties icon .
On the Data Sources tab in the Data Sources and Drivers dialog, click the Add icon () and select Apache Derby.
From the Driver list, select the type of the JDBC driver that you want to use. For remote connections, select Apache Derby (Remote). For embedded databases, select Apache Derby (Embedded).
Check if there is a Download missing driver files link at the bottom of the data source settings area. As you click this link, RubyMine downloads drivers that are required to interact with a database. The IDE does not include bundled drivers in order to have a smaller size of the installation package and to keep driver versions up-to-date for each IDE version.
You can specify your drivers for the data source if you do not want to download the provided drivers. For more information about creating a database connection with your driver, see Add a user driver to an existing connection.
Specify database connection details. Alternatively, paste the JDBC URL in the URL field.
To delete a password, right-click the Password field and select Set Empty.
To ensure that the connection to the data source is successful, click the Test Connection link.
(Optional) If you are connecting to a data source that contains a lot of databases and schemas, in the Schemas tab, select the schemas that you need to work with.
Click OK to create the data source.
