Bill Inmon's Data Warehouse 2.0 tackles industry trends, unstructured data and the data lifecycle

Of all the mainstream business technologies, classic data warehousing might well be considered the least evolved in terms of practice and approach. And while data warehousing continues to spread as a foundational technology, the availability of information and speed of change have led businesses to add operational data strategies to the data warehouse mix - something the textbook writers didn't originally envision. So it might well be left to one of the fathers of the industry to update the definition of the data warehouse. That person is Bill Inmon, president of Inmon Data Systems. His model - called Data Warehouse 2.0 - is delivered with a complete architecture, outright enthusiasm - and a little ambivalence. You'll find the technical details in Inmon's recent articles in DM Review and at his Web site,; more recently, DM Review Editorial Director Jim Ericson spoke with Bill Inmon for a philosophical take on DW 2.0.
