Summary: For when you wonder, how should I model that....
Comment: This book provides excellent starting points for modeling basic business functions. I have found when modeling that it helps to ask another DBA's opinion on how they would aproach the same business process or data segment. This book serves as that second person. It provides proven models that can be effective for your own modeling activities. It is well worth the investment and then some.

Summary: Excellent resource of data models and physical designs
Comment: The Resource Book is one of the more useful books I have seen on data architecture. It is just what it says: an (excellent) resource library for seven logical data models, one warehouse design, and two data mart designs. These data models and designs can be used as templates or starting points for your own modeling, an introduction to subject areas you might not be familiar with, validating your existing models, and a help to building a corporate data model. The logical models tend to be very complete. You probably won't need all their features, but they provide a good reference.

The book provides a good notation for showing the relationship among high-level models, mid-level models, and data warehouse and data mart designs. Instance tables (sample data) help bring the models to life. The book also provides a good methodology for transforming logical data models to data warehouse designs. The book is an extremely useful resource.

Summary: good for a start, but...
Comment: This is a good book to get the juices flowing if you are unsure of how to model certain business processes, but some of the models in the book are poor examples of database design. Some of the data warehouse models, in particular, are alarmingly bad, and don't follow some proven best practices.

I think the beginner database designer will get a lot out of it -- seeing the complexities in database design. The expert will get a little from it -- a good kick-start on a design, but you will be able to see the faults. Someone with a little knowledge that relies on this book too much, however, will be sorry.
