Dennis, if you mean a common (for the enterprise) data vocabulary (what is what and how it relates to others), I am with you.

Data models can be defined on many abstraction levels, and when people are talking about using a common data model they often mean very different things. I believe in using a common enterprise data model as one of the cornerstones when integrating systems or creating services, but I'm not talking about a detailed data model, rather something like your MDM approach or even higher abstraction levels. I've found this high level common enterprise data model being very effective at creating a common understanding of important concepts and information in an enterprise. // Dennis Djenfer Sounds like the On 2010-06-22 22:04, Steve Jones wrote: > > >Not really as MDM isn't about the full model its about the core and >identifying duplicates and commonalities.
