Now, now.

I guess what your message here is that hierarchies model the "real world" more accurately. I would dispute this. (Apologies if I got your message wrong.)

What formal method can we use to measure how well a data model models the real world? I would claim there aren't any. If I'm right, then it's not useful to claim how well one or another data model matches the "real model". Rather, it makes sense to analyze the data model itself, and search out its strengths and weaknesses.
