Bidirectional relationship
In the standard case, relationships are always defined as bidirectional, so that both sides
of a data group can navigate to the referenced data group. If this should only be possible from the source data group, a unidirectional
relationship can be defined. In the latter case, no navigation property will be added to the target data group.
