Composite Diagrams...

So this is a more academic discussion today...

I am used to Physical Data models or Logical Data models which are pretty rudimentary. Are these composites? In a diagram sense, Yes.

What does that mean? They combine a list of information:
classes, entities, attributes, columns, tables, etc...
whatever terminology you use in your modeling tool. These lists are then organized into visual representations, which become composites. So why am I talking about this...

The basics lists that are created are VERY important, and I see architects forgetting that all the time. They will use two diagrams and create the SAME attributes over again, rather than using the shared or copied attribute from a base list. Now their new diagram is going to differ from the other one since they can change the Definition of the new attribute without having some basic understanding of how that information, or object, should be bounded... UGH>

anyway, will chat on this more later and maybe get a few screenies for the post.
