I agree with that. 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.

Not really as MDM isn't about the full model its about the core and
identifying duplicates and commonalities. So for "Person" for
instance it might only be 25 attributes that are used by MDM to do
that. The other 300+ attributes that exist around the enterprise
aren't included within the MDM model.

Steve,
In your blog you write:
"The only sensible policy is to look at an "active" MDM strategy
and a brokerage approach to communication between systems ideally
based around a federated data strategy that leaves information its
its source systems but provides references between them."
Where does the data model for the active MDM strategy and
brokerage approach come from? Isn't that the same model as you
would use for buidling a canonical data model?

Hello all.
I have a question for the design of a canonical data model.
The issue is that I want to create a data services layer, and
for making the design of services that expose data, first I
want to create the canonical data model, which allows me to
properly design services, and I want to know if this
canonical data model should correspond to the data model of
the database, E / R model , or I just model the information
concepts that are handled in the database.
