Just finished my reading of this book. I enjoyed the way the author explains the terminologies about data modeling. I have years of database development experience. Although this book covered the topics mostly for beginner, I found it is benefited to experienced data modeler too – it refreshes the fundamental about data modeling.

4.0 out of 5 stars Data Modeling 101 May 12 2009
By Joseph Reddy - Published on
Format: Paperback Verified Purchase
Data Modeling Made Simple comes in at a lean 132 pages that effectively provides clear understanding of high-level concepts involved in data modeling while holding off on the low-level details to be covered by other books.

As a developer who approaches a database as just a backend to my business application, I gained further respect for data modeling, even as a parallel process to object modeling. Most of the author's statements of purpose and benefits of the data model match the purpose and benefits of an object model. I believe that doing both only gains me more insight into the business which is of course invaluable.

On more than one occasion after the author suggests something I found myself thinking, "I hope he explains other situations where you would not want to do that!" And almost without fail two sentences or paragraphs later he explained the alternatives or downsides to the suggestion. To me this is a hallmark of any good book on technology and methods. In fact, just to be picky, I only recall one time he did not do this. After explaining that we might denormalize a database to make it more user friendly (among many other reasons he goes in to) he then states that we might want to use an integer as opposed to a 10-character code for a surrogate key on an entity because the integer is more efficient. That's true, but I was expecting him to state the tradeoff that the 10 character code is much more user friendly, more easily read. However, as I said earlier, I think most tradeoffs that I thought of were all covered in the book.
The book is definitely an introduction book and never claims to be more than that. The title even states it is just a simple, practical guide. The chapters are laid out as common questions someone might have about data modeling which makes it an easy read and an easy reference. I will recommend this book to new developers as a quick intro to data modeling and to help arm them with good definitions of terms and high-level explanations of common concepts that they need to understand. I will also recommend this to mid-level and senior developers who still seem to have no basic grasp of data modeling concerns and methods. And lastly I will recommend it to those who seem to think there is a huge gap between object modeling and data modeling in the common business application.

1.0 out of 5 stars Superficial and way too "simple" Sept. 14 2008
By Glen B. West - Published on
Format: Paperback Verified Purchase
Upon taking on the role of Data Architect, I needed to get up to speed on data modelling, beyond the simple ERD (Entity Relationship Diagram) that is the staple of the trade. This is a small book, and even though it was clearly superficial, I actually took the time to read word for word, because I was hungry for something I didn't already know. Specifically examples of other types of models. This was the VERY basics, only useful to someone who knows nothing at all about data, databases, and data entities. If you are absolutely clueless, this might provide some basic foundation for further study, and I was unable to find anything better on Amazon. This is a topic that is not well documented, as best I've been able to tell.

If you study UML, you will get a better understanding of the mechanics (not the reasoning) in their data modelling chapters. I have yet to see a good model discussion that explains the difference between logical and physical modelling (this book's explanation was very light and zero examples), the role of the data owner, retention, security, how it's used in the applications, any of those architecture issues that should affect a model.

The author did a good just in explaining in a simple way the sometime complexe world of data modeling.
I recommend it.

1.0 out of 5 stars Terrible book. Don't waste your money. Seriously. July 2 2008
By J. Sipiceanu - Published on
Format: Paperback Verified Purchase
The word "pain" comes to mind when reading this book. I was
looking forward to find out what a "master" data modeler might have
to say and the knowledge imparted. I was disappointed within the first
couple of pages. The second huge word that comes to mind right
from the start is "confusion". Unless you are a database guru
you will find the explanations in the book utterly confusing.
To give an example: the concepts for candidate key, primary
key, alternate key, surrogate key and foreign key are all
explained within the length of 1 page! You tell me you've
mastered those concepts by reading only 1 page (page 30)?
Are you kidding me? What is the author thinking? Is this a
dictionary or a book to learn from?
Data modeling can be quite complex especially when it borrows from
data base concepts. When data modeling is made "Simple"
(as the book's cover states) then it becomes useless.
As useless as this book is.
Seriously! I'm not trying to knock it. I'm just being straight forward.
This book does not explain anything that a person can pick up
and say: "oh I understand that", "it's clear to me". Surprisingly
disappointed. Sad book. Is there something less than 1 star?
(And I actually read the reviews by the other people who gave it
5 stars before I bought it).

1.0 out of 5 stars Worthless if you already know anything about data modeling July 8 2008
By Rabbit Hill Manor - Published on
Format: Paperback Verified Purchase
Mislead by other reviews. Covers only basics of ERD style modeling. Not current with any UML approaches. If you only do Oracle and have never modeled, this might be a good start. Would have returned it if I could.
