I have trouble understanding your question, especially why you pose it
in such an abstract manner.

It's your data you're talking about, right? Well, then you'd better know
darn well how they're related. Once you have established what those
relationships are, you map them. There ain't many candidates. You've got
many-to-one, one-to-many, unidirectional one-to-one and bidirectional
one-to-one relationships. That's about it.

Your starting point must be to analyse what you're modelling, methinks.
