When creating an association between two entities, it is not possible to specify the future primary key of the association.
For an 0..N cardinality, the entities identifiers will be added as foreign keys into the association table, but then the physical model must be edited to add the primary key of the associative table.
This will have to be done every time the the logical model is updated.
An alternative way would be able to update a physical model from an existing logical model.
