Select the DDP source application type from the Source Application node in the tree menu to display the source application instances. Click New to create a new instance. The name for the source application is the only information required for a DDP source application. However, the name is important because when data is published to QXO, the sending application must supply the name entered here so that QXtend knows which instance the data is for.

You do not have to define a set of database connections for DDP source applications because the database is used by the event service and DDP does not use the event service.
