Academics Say Enterprise Data modeling Sucks Big Rocks
In practice, it's all but gone. I hardly ever hear anyone mention EDM any more. Just the odd case that crops up here and there.
The value has really fallen to defacto models that are getting built up inside the metadata repositories of DI/ETL products, and in the user-based models.
Really EDM was aiemd at too many problems. It didn't solve the IT problems of systems/data integration because it's the wrong approach. It didn't solve the user/IT problem of finding data which is being addressed through data warehousing, BI, portals and various metadata-driven tools like EII.
EDM is much like the data modeller's version of "ERP will solve the integration problem." That didn't work either.
