I pointed out last year that the grand central enterprise data warehouse couldn’t happen; the post started:
An enterprise data warehouse should:
- Manage data to high standards of accuracy, consistency, cleanliness, clarity, and security.
- Manage all the data in your organization.
IBM’s main theme at the Enzee Universe conference has been to say the same thing.
Merv Adrian’s talk at the same conference made it clear that Gartner feels the same way, as does he personally. Indeed, like me, he’s racked up multiple decades of industry experience without ever finding a single theoretically ideal grand central EDW.
Forrester Research has been a little less clear on the point, but generally seems to be on the correct side of the issue as well.
If somebody is still saying that one central enterprise data warehouse can hold all the information or data you need on which to base your business decisions, they’re probably not somebody you should be listening to very hard.
Is that clear, or should I hammer home the point even harder?
