The chapters in the book are divided into 5 sections. The chapters in each section end with an exercise and a list of the key points covered to reinforce what you've learned. I find myself comparing the teaching structure of the book to the way most of us learn to swim.
SECTION I: Data Modeling Introduction
The first section is like the shallow end of the pool, where as a beginning swimmer, you can dip your toes in to test the water. These easy chapters are short and concise. Here the author uses very common objects to describe what a data model is, and why it is so valuable. His first examples made excellent use of what's truly a universal data model to millions of computer users in school and business: the spreadsheet.
SECTION II: Data Model Components
In the second section, Steve Hoberman introduces you to the simplest components that make up a data model, and explains the important terms that we apply when we discuss them. By the end of section 2, you now have both feet comfortably in the water. You're ready and eager to plunge deeper into the depths of this pool of data model knowledge.
SECTION III: Subject Area, Logical, and Physical Data Models
You've made it to the deep end of the pool where you get a real workout as you lap through the 3 levels of data models: subject area (or conceptual), logical, and physical. Just as there are different strokes for different folks, there are different models for different audiences. By the end of section 3, you'll be able to swim through the intricacies of a data model like a barracuda.
SECTION IV: Data Modeling Quality
Just as swimmers can kick-start their movement through the water with the use of swimming aids (maybe a flotation device or fins will help), you can utilize Steve's 4 favorite templates to collect and organize the requirements that will define your data model. You may recall the scorecard the Olympic judges use to rate a dive. Steve introduces his Data Model Scorecard, which applies a quality rating to a data model. It's an objective look at the quality of the model built. We are actually adopting this tool where I work, after applying our own weightings to his 10 criteria.
SECTION V - Beyond Data Modeling
Believe it or not, you're ready to leave the pool and jump head first into a small part of the ocean of outside influences that affect a data modelers' work. Bill Inmon tackles unstructured data with taxonomies. Here he simply provides the best explanation about taxonomies and ontologies that I've found. Michael Blaha, who literally wrote the book on the subject of the Unified Modeling Language (UML), follows with an introduction about UML. Steve ends by answering the 5 most frequently asked modeling questions that he has encountered.
This revision took the first edition up several notches from what some deemed a data modeling for dummies book, to what is now a full-fledged textbook. It's easy to see how it could quickly and easily light the way for many future data modelers in any classroom. I have it on good authority that the author wrote this book to be the most easy-to-read and comprehensive data modeling text on the planet. I agree. This is in itself a wonderful way-finding tool for data modelers that's very easy on the eyes and complete in its coverage. --The Data Administration Newsletter (tdan.com), by Johnny Gay

Ouch. This is bad. From presentation to explanation, it's bad.Published 3 months ago by Incredible Mouse
I like the author's use of imagery to describe data modeling (the camera analogy he uses throughout). It makes the process "come alive" in a very practical and useful way.Published 13 months ago by Stuart J. Shepherd
This in an excellent and easy to follow book on Data Modeling. It is good for novices. I would highly recommend it!Published 15 months ago by CD music collector
The author reviewed a great book called Star Schema The Complete Reference, which I thought was a great book. He mentioned his book to compliment Star Schema. Read morePublished 16 months ago by Jack Bisson
This is a beginner or introductory book, great for a first time exposition to the topic. I bought it as a refresher and found it very basic.Published 18 months ago by Rodolfo Q. Z
I have been developing data models for over 20years and have read a number of texts on the subject. This is an excellent introductory book on the subject. Read morePublished 23 months ago by Timothy A. Adams
I found this book accessible and clear in its descriptions. It would definately be useful for either a technical person new to data modelling and for non-technical people wanting... Read morePublished on July 30, 2012 by CollectedReader
