A Maturity Model for Data Integration

Integration is an odd thing.  You have to make many people agree on common things in order for it to work.  If you look at the things that people agree upon, you can see where you are in data integration, and where you still have to go.

I'd like to lay out a maturity model for data integration:

Level 0 - no elements in common. 

Languages, reference data, assumptions... all different.  Integration can only occur in the data warehouse and then only after each data source goes through a mapping and normalization process.&n
