1.0 out of 5 stars
Flawed Academic Overkill,
By David Hedrick Skarjune "Word & Image" (Minnesota, USA) - See all my reviews
This review is from: Database Systems Design, Implementation, and Management (Hardcover)
As a professional database consultant and college instructor, I found this textbook to be an academic exercise that is flawed in defining basic concepts and filled with useless details.While Rob and Coronel are listed as the authors, it's obvious that this was a departmental project at the Middle Tennessee State University, where they teach. The writing style is one of boring exposition perfomed by a team of writers against an arbitrary outline. It's incredible that a 750-page university text in 4th edition has inaccurate definitions and misleading examples of the basic concepts of the field. They don't event get 1st Normal Form right...as they show data in redundant rows and call that "repeating groups." For Transactions they give the ANSI definitions for COMMIT and ROLLBACK and then claim that they don't need to be used if "the application terminates normally." So, does that mean we should only use transaction processing when we write SQL with the intent to make applications that abend? The book revels is lots of useless details, providing more quantity that quality. Oddly, while the authors present themselves as Oracle experts, all the data shots (and accompanying databases provided on an instructor's CDROM by publisher Thomson Learning) are rendered in Microsoft Access. Many of the problems provided at the chapter ends are literally impossible to complete. How can a student normalize a one-row data sample with no business case or rules? How is a student supposed to derive exact Semester beginning and ending points from a list of random dates? Apparently, the editors didn't bother to have anyone attempt solving such problems. This textbook does not provide adequate training for basic SQL, professional database development, or serious database administration. I was forced to use it for college classes, and I supplemented with more outside material than I could cull from the text. It's not enough to allude to things like triggers and stored procedures--you have to actually write them in the real world. There are many other database books to choose from for both theory and practice.

How to make heavy stuff seem light,
By Jan (Norway) - See all my reviews
This review is from: Database Systems: Design, Implementation, and Management (Paperback)
Designing databases is hard work and involves a lot of thinking. This books makes it easy. It's very explantory, uses real-life examples, and encourages the reader to do some studying on his own. However, I have to deduct one crown...the book would be even better if it came with a CD-ROM. Typing all examples by hand into my PC may be the right (and hard) way to learn, but it's tiring.

Comprehensive, but perhaps too much so,
By
This review is from: Database Systems: Design, Implementation, and Management, Fifth Edition (Hardcover)
First let me just say I liked this book. Why? Because it is a pretty IT book with useful and informative color screenshots and illustrations that are explanatory. It is of course both fortunate and unfortunate that the author uses screenshots of MS Access databases almost exclusively.I do wish the author had spent more time discussing web-database application integration. Also, he only used Coldfusion (the most expensive variety) to illustrate web-database interactivity. This is great for learning some basic Coldfusion tagging, but how about something useful for small-time web hosters and others who want to use PHP, which is not only free but more powerful than Coldfusion. Ah well. This book is very large in height - you'll see what I mean when you pick it up. The sections on ER diagramming, SQL, normalization, and design are top notch. However when the book gets into the later chapters, and covers more difficult subjects such as distributed database apps, transactional databases and Internet-related topics the coverage becomes a little weak. He does give a fine overview of all the topics presented however and the book is not totally boring to read either. The author is very lucid. I recommend this book as an introductory text on databases but nothing more.
