Data Warehousing Architectures Must Reflect Business Consensus
The Nature Of Information Must Command Decisions Over Physical Architectures
by J. Paul Kirby
with Keith Gile, Connie Moore, Lucy Fossner
Executive Summary (This is a document excerpt)
Data warehousing architects have several popular architectures to choose from. The choice of architecture guides how many database instances they will have and how the instances should be connected. Missing, however, is a framework for deciding what types of information should be put in those database instances. A Consensus-Based Modeling Architecture (CMA) organizes information based on whether an organization has reached consensus that the information is universally applicable. This promotes a single version of the truth — but only where it is warranted. CMA acknowledges legitimate differences between definitions, and it protects different business interests from each other. The end result: quicker compliance with business requirements and long-term architectural coherence.
