Re: [xml-dev] XML Schema as a data modeling tool
Well yes, that was hyperbole, in the e-mail prior to this I pointed out you'll never get to that point.  However, I  think you miss the point; this can be domain specific.  If you're a phone company then it is quite likely that your Enterprise data model pretty much encapsulates everything you need to know about phones in order to do business with the phone company and build applications dealing with phone related data.... 

But no, the point of a good model is not to simplify things so that a single brain can grasp it.  A good model will be able to provide both summaries simple enough for a single brain to cope with and simultaneously hold the detail that drives a development department of 1000+ people (not uncommon at a phone company).

What do you do with an Enterprise ready data model?  Anything and everything you want to do with the given data domains in the given Enterprise!  By definition, the model is good to go for any task you throw at it and requires no more manipulation.

If that were really true, it would have to contain every detail of every data type used within the organization.  That's not a model, it's real life.  The point about a model is that it simplifies real life so a single brain can grasp it.  Otherwise you wind up with Wikipedia at best, and complete chaos more probably.
