5.0 étoiles sur 5 Beware, it really isn't for dummies at all! Covers a lot of ground / A good primer. 15 août 2011
Par jimmy dean - Publié sur Amazon.com
Don't let the "for dummies" part fool you, this book is great even if you've been using SQL for years. I picked this book up because I read reviews saying this is far too advanced for a beginner. I can't speak for beginners, but it was great for me. I'm an intermediate level software engineer, and I have built more than few databases already. However, there are gaps in my knowledge, and I found this book helpful for getting myself more up-to-date with SQL concepts from schema design to performance tuning.

I particularly enjoyed his description of all the standard SQL data types from char, varchar to national char, blob and clob. There are some nuances between various data-types which I was a bit hazy on, but this book cleared that all up. He does a great job explaining things like indexing and how to tune up database queries. He touches on some advanced concepts like EF Codds normal forms, and explains some of the differences, and even tells you which normal forms are too obscure to really be relevant for most database systems. He also explains why de-normalization matters and how to find that "sweet spot" between performance and robustness (resistance to modification anomalies).

If you're not already familiar with RDBMS concepts like relations, attributes, tuples, ER models, and such, this book may be a very valuable read for you. I'm giving this book 5 stars because it gave me exactly what I wanted-- about 640 pages summarizing all the important concepts of SQL, plenty of real life examples, and illustrations as well.

5.0 étoiles sur 5 Not so dumb after all 6 octobre 2012
Par Personne - Publié sur Amazon.com
I've been aware of the 'For Dummies' books for years. After several decades in the technology business, it's perhaps understandable why I've shied away from opening one. I'm not a dummy--there are simply things I don't know. But I found myself in the position of needing to know just a bit about SQL. So I donned an appropriate disguise and snuck into the library.

What a surprise. This is an excellent book, sitting astride the area that goes from basic introduction well into hands-on. It's written clearly without a hint of the condescension I feared. It does assume some technical background, but the author has a good sense of where the reader's knowledge is likely to end. I was impressed with the overall organization. It's 8 books (sort-of), with the goal of each well-delineated. Each volume has a clearly stated purpose and is written with a clarity that is rare among technical writers.

For those of us willing to admit an occasional bout of dummyhood, this is a fine antidote.

5.0 étoiles sur 5 Good guide for beginners 18 mars 2013

I started reading this book without much knowledge of SQL. My background isn't IT, but I work closely with systems and wanted to learn more on the side to help me with my job. This is a great guide. It's easy to follow and understand, moves along quickly, but it doesn't dumb down the material. Also, the 8 books in one encompass a lot of knowledge about SQL and databases. This is a good resource.

This book explains a lot about SOL, and it makes clear much of what you wish you understood better in other books. When you pick up your expensive SQL text, don't forget the "...for Dummies" book to go along with it.
