Name and alias can be defined for the relation. The Parent Data Source (21) is the data source that the connection should be built on. The Child Data Source (22) is the newly added external data source.

In the box Parent Columns (23) the box of the parent data source must be selected to which the connection relates. In the Child Columns (24) the connection box is defined from the child data source.

 

 

If the relation is built, the external data source is integrated into the template. This occurs again by adding the data in the page area.
