Looking at all the questions you have asked around this subject, it becomes clear we forgot to ask you the most important question: what are you trying to accomplish? What are you building? What is the original (customer) requirement?

You are asking bits and pieces about relationships, workflows, etc, but combining all those questions makes me wonder if the correct approach has been taken.

If my answer helped you in any way, please then mark it as helpful.
