I've found that while this works in theory, in can be extremely fragile in practice. All of the wonderful tools floating around this list and others that generate code based on one or more of these design artifacts are very helpful, but usually require at least some manual tweaking. But that's just my point of view - I prefer a little more explicit code than "magic" - in my opinion, definitely easier to debug and extend. > I thought it was best practice for an object to know everything about > itself.

My business objects know quite a bit about itself - all of its attributes and methods it uses to accomplish business. However, it doesn't know about persisting nor reporting, which I've delegating to DAOs and Gateways respectively. To each their own, I suppose - Ray Camden's excellent blogCFC keeps everything together, though when I tried to tweak it a little bit, I found that having all of the persistence and gateway methods in the same object made it hard to read and confusing.
