Hi,

I agree with the global Global Conceptual Model schema. I think when you design a IT system you need to have an easy way to look for the global conceptual schema. With a Global conceptual schema you can see the interception between of Data and DataFlow's by functional areas. I use to create Global schemas and smallest schemas by functional area. This aproach give me a Global View and a View by area.

A major advantage of this stratagie is refered by YORDON in "OO
Management Project's" like the only way to your client read your Analysis material. As you Know the client opinion is one of the most importante facts in a project

Bye,
