Re: IDJIT! Your Data Model Can't Posssibly Work!

I again find myself amazed at how difficult it can be to make a simple point. Actually, Bob's
synopsis of my post is accurate. Yes, I did say that the Halpin's (I mistakenly referred to
him as "Halpern.") ORM* could be helpful - but only to the extent that it sets a different
framework within which to analyze the real world than the Entity-Attribute-Relationship
approach does.

I also misunderstand what OP meant when he said that an attribute could suddenly have
more than one value. Looking over more of the posts in this group, it seems that I failed
to recognize some of the "code words" used by the multi-value attribute gang. Bad on me.

I think that the "OP's originally situation" was caused by poor design.  That better designs
are able to meet changing requirements. That careful attention to entities results in better
designs. That "relationships" and "roles" are unreal and efforts made searching for them
result in distractions. That studying the events that transform entities is more useful. That
it will soon be obvious that too much time has been wasted on this topic.

• Object-Role Modeling. That OverRelational Manifesto was tough to take. The laudable effort U-Gene made to present his ideas in English kept me turning the pages thinking, "Maybe he's using the wrong words" and "Maybe he's not using the words I expect." When I arrived at the end, though, I found myself asking, "WTF was *that* all about?"
