Is it just me, or is there something wrong with how the
"orgpeoplemembership" box was drawn? Apart from that, it
seems to work nicely -- it's awfully big, but then so is the
schema... (I guess I would have preferred a different way
to draw the lines and arrow symbols for the foreign-key
dependencies -- having the lines look more like those in the
OP's image, extending horizontally from each box where the
field in question in printed -- but that's just a nit-pick.)
