Average Reviews:
(More customer reviews)I also am a reviewer of the book and an interested colleague. I've used this book since its first edition as my main reference on basic data modeling, and I have been happy to comment on its newer editions. This 4th edition improves on earlier ones by including the Unified Modeling Language (UML), my own first choice for a design language for data modeling. The chapter on the UML includes everything you need, but it keeps it as simple and straightforward as possible, making the material very accessible. The real contribution of the book is in the normalization chapter and in the excellent description and examples of n-ary relationships and the consequences of their multiplicities, a very-hard-to-understand corner of the data modeling world. The inclusion in this edition of material on OLAP and data warehousing is also welcome, though very limited in scope. Finally, moving the physical design material into a separate book makes this book much more cohesive and useful as a reference for data modeling.
