    CMP 2.0 Unidirectional 1-1 mapping

    Frank Adcock Newbie

      In a 1-1 mapping, does it mean object A has a direct relationship to an instance of Object B, and that another instance of object B has a direct relationship to a different instance of Object B.

      My understanding of 1-1 mapping is that each instance of object A can only have a relationship with one instance of object B, but they can be different instances.

      The reason for the question, is that I have a setup that works with a 1-n mapping, but I believe should be 1-1 that seems to get confused about the relationships, particularly in unidectional state.

      Is my understanding about relationship multiplicity correct ?
