If you are in data modeling and database area, believe me, this is a must read. It is about the philosophy of data modeling and how data and reality are related. In my opinion, its content cannot be obsolete. It is technology independent. The concept of naming and identification alone is priceless for data modelers. I can't believe I have been working in the database area for more than 30 years without it.
The second aspect of above statement concerns how we know and communicate information within organizations. However, and most importantly, the broader topic is worth the investment of the reader's time, even though it bridges over into Philosophy.
The bridge to philosophy is tempered by the authors many years doing practical the practical work of data modeling, shaping the professional organizations which develop IT standards and interacting with thought leaders in information systems and the philosophy of knowledge.
Steve Hoberman's additions to the original work by Kent clarify and make accessible this important material. In addition, his contribution gives Kent's classic work a current day perspective.
For IT people who want to take data modeling to the next level or even for the executive who makes organizational decisions concerning information this is an important book.
I have to admit that I had to read the earlier version book three times and the reality came about when I reviewed my models and other models against the backdrop of the perspectives described in the book and attempted to apply some of the ideas William has put forth.
What is also helpful is that William did not attempt to put forth singular solutions, but describes the problem in detail so you can appreciate all the perspectives before deciding how to deal with the problems and challenges in an informed way. When dealing with data, ignorance is not bliss. Reality should rule.
For example if you have to model roles and relationships you will attest to the fact that there is no best solution. Other books provide prescriptive solutions that eventually limit the use of data. They are too simplistic. William looks at this problem from a distance and then delves into the microscopic view. It provides a Grand Unified Theory for data.
This version of the book offered me an opportunity to renew my understanding and appreciation for data and with the additional content provided by Steve Hoberman, some helpful examples and clarifications of the concepts. More reality.
Anyone in the field of data including data architects, designers and developers should read this book and internalize the concepts and issues identified in it. Only then will you have a "real" perspective on data.
His exposure and description of relationships and how to address them was enlightening.

A study group book. Good discussion but everyone pretty much agreed it was too vague and out of date.Published 16 months ago by George D. Girton
I found this book following a reference from a Martin Fowler book.
It's been a while since I read it, very interesting discourse on modelling data.
