Concept

The "One-to-Many" relationship enables to add a tab reprensenting instances of another entity ( that exists or not ) in order to create a link between them.It is thus possible to create instances of the target entity that is linked to the primary entity.

If the target entity doesn't already exist, it is considered as a sub-entity.A sub-entity is not displayed in the left menu but has the same functionalities as a standard entity ( creation form, update form, list, delete button ).
