Disappointed.
Mr. Giovinazzo, titling this book Object Oriented Data Warehouse Design is quit a stretch. True it does contain the Object Oriented buzzwords, but no real practical OO design or implementation information. A better title would have been 'Introduction to Data Warehousing' but then this would just be remake of a hundred other books already available on that subject.

A good difference that sets it apart
This is the one book that will explain to you what data warehouse design is all about. Many books have been written on relational database design. Many other books have been written on data mining. And so many others on data warehouse design. Yet data warehouse has been so little understood. It may be because there are too many good books on relational databases and not so many good ones in data warehouse. With this one book the scenario may change. Finally people will not have any more excuse to say that they do not understand what a good data warehouse should be like. And, most importantly, how much it differs from the well-known relational databases.

Design perspectives and ideas
What this book offers is perspectives on designing warehouses with the goal of "business intelligence". Particularly useful is an interview process of extracting requirements from the end users, business strategists, upper management, and IT support people. Giovinazzo, also introduces the topology of multidimensional databases (e.g cubes, stars, and snowflakes) and the use of "fact" tables to tie these dimensions together. Through the use of the "Big Brother and the Building Company" example, he provides some down to earth examples. In a few appendices he introduces spatially enabled warehousing (weakly), metadata standards and good tips and tips on extraction, transformation, and loading. These alone are not "minor subjects", but warrant the introduction given here (and subsequent books). The books title includes "object oriented" but is perhaps not emphasized enough. I think the real value is getting the designer to think about the needs and dimensions early in the process.
