DW 2.0: The Architecture for the Next Generation of Data Warehousing (Morgan Kaufman Series in Data Management Systems)
Data Warehousing has been around for 20 years and has become part of the information technology infrastructure. Data warehousing originally grew in response to the corporate need for information--not data--and it supplies integrated, granular, and historical data to the corporation.
There are many kinds of data warehouses, in large part due to evolution and different paths of software and hardware vendors. But DW 2.0, defined by this author in many talks, articles, and his b-eye-network newsletter that reaches 65,000 professionals monthly, is the well-identified and defined next generation data warehouse.
The book carries that theme and describes the future of data warehousing that is technologically possible now, at both an architectural level and technology level. The perspective of the book is from the top down: looking at the overall architecture and then delving into the issues underlying the components. The benefit of this for people who are building or using a data warehouse can see what lies ahead, and can determine: what new technology to buy, how to plan extensions to the data warehouse, what can be salvaged from the current system, and how to justify the expense--at the most practical level.
All of this gives the experienced data warehouse professional everything and exactly what is needed in order to implement the new generation DW 2.0.
* First book on the new generation of data warehouse architecture, DW 2.0. * Written by the "father of the data warehouse", Bill Inmon, a columnist and newsletter editor of The Bill Inmon Channel on the Business Intelligence Network. * Long overdue comprehensive coverage of the implementation of technology and tools that enable the new generation of the DW: metadata, temporal data, ETL, unstructured data, and data quality control.

Awareness of this book arose following my recent reading of a white paper on Data Vault data modeling by Dan Linstedt that a recent client of mine had suggested. And although I was not impressed with that white paper, what I found intriguing is that Lindstedt quotes Bill Inmon as saying that "the Data Vault is the optimal choice for modeling the EDW in the DW 2.0 framework." Thus the acquisition of this text by Inmon. Almost everyone vaguely familiar with this industry space is probably familiar with Bill Inmon and Ralph Kimball. What is interesting is that Inmon, the "Father of Data Warehousing", is credited alongside two other individuals with writing this text. It is not transparent as to who actually wrote most of the content for "DW2.0", but what is quickly apparent is that most of the statements contained in the book are generalities, and the vast majority of the diagrams are deplorable, consisting mostly of inferior clip art that adds little to nothing to the discussion.

First of all, this book is not written with the DW novice in mind. Some of the chapters require a thorough understanding of DW theory and concepts.
Generally I found the book useful and I got some ideas that I will apply in one of my next projects. The biggest weakness of DW 2.0 is its lack in detail. In a lot of areas I found the book to be patchy and too high level. In my opinion DW 2.0 as presented in the book is not (yet) an elaborate data warehousing methodology.
What follows is a discussion of some of the more interesting concepts and chapters in the book.
(1) The different sectors of DW 2.0
To me it did not become fully clear what exactly the Interactive Sector is. Is it a cumulation of an enterprise's operational systems or is it a real time replication of these systems as an additional physical layer? A practical example really would have helped here. Personally I have my doubts if all the operational reporting requirements can be... read more
Book is built on hype but no substance

I bought this book because it had good reviews, however, after reading it I was extremely disappointed with Inmon as it does not appear to be a detailed discussion about data warehousing at all, but an over hyped book which tries to explain fundamental data warehousing techniques in a way that you would explain to a baby (repeated a thousand times and with diagrams of various shapes including triangles, circles, and squares). Seriously! Triangles, Circles and Squares!!!
This book is way overpriced for what it is and the fact that Inmon's name is printed on it, does not mean that the book follows Inmon's traditional data warehousing books. This book is different because it does not deliver much content nor does it deliver any new concepts, breakthroughs or strategies of building data warehouses today.
So whats in the book? Honestly, not much. Just very simple concepts scattered around the book in such little detail that it would be impossible to implementation or... read more
