Creating a data connection

You can create a data connection in any of the following ways:

• Use the Connection tool in the diagram Palette.
• Select Model→Data Connections to access the List of Data Connections, and click the Add a Row tool.
• Right-click the model or package in the Browser, and select New→Data Connection.

When you create a data connection from the Browser or from the List of Data Connections, you must have previously defined source and destination objects for the data connection.
