Level 3. Central Repository

  • The EDW is the central repository of ALL historical data in the enterprise.

  • If it creates data, it dumps to EDW.

  • People that were regular customers at level 1 are now data addicts and get testy if they don’t get their fix.

  • The thing that nobody cared about months ago is now critical to daily operations.

  • Appropriate master data management has been implemented and data from disparate systems is seamlessly combined to deliver an integrated 360-degree view of the enterprise.

  • EDW now exist as a platform/ecosystem instead of an atomic standalone element of enterprise architecture.
