# Configuring Connection Settings

Before using a data source, the connection to it must be configured by creating a connection string.  To create the connection string for the data source which can then be used as a Source or Target,  follow the instruction below:

1. Select Connections from the Settings menu.
2. Click the **New** toolbar button to select a connector  and enter a name for the data source.
3. Configure the properties of the connection string by entering values when prompted and selecting available options.
4. Test the connection.
5. Use the **Save** toolbar button to save the connection definition.

The following toolbar buttons are available on the property grid for completing tasks:
