Data Warehousing is one of the most important areas of consulting for The Ken Orr Institute. Ken Orr has been working in Decision Support and Management Information for the last 30 years and in Data Warehousing since the late 1980s. This technology has taken off in the last few years. One of Orr’s major contributions has been in the area of Enterprise Data Architecture, and KOI has recently announced a new version of Ken Orr’s Enterprise Data Architecture (Version 3 ). This version shows explicitly the various forms of users and providers of data that are involved with the data architecture. Most of the layers are roughly the same as our earlier Data Warehousing Technology Whitepaper.
