There are 3 types of External Metadata Objects in Rollbase: DataDirect Cloud, OpenEdge Service, and External Database Tables. For all of these you can create relationships between Rollbase native objects and the external ones... the limitation is that they need to have a Primary Key defined. Basically Rollbase creates a 'relationship' from the native object to the external one by creating a foreign key in the native object.
