Reseña del editor
Database System Concepts by Silberschatz, Korth and Sudarshan is now in its 6th edition and is one of the cornerstone texts of database education. It presents the fundamental concepts of database management in an intuitive manner geared toward allowing students to begin working with databases as quickly as possible.
The text is designed for a first course in databases at the junior/senior undergraduate level or the first year graduate level. It also contains additional material that can be used as supplements or as introductory material for an advanced course. Because the authors present concepts as intuitive descriptions, a familiarity with basic data structures, computer organization, and a high-level programming language are the only prerequisites. Important theoretical results are covered, but formal proofs are omitted. In place of proofs, figures and examples are used to suggest why a result is true.

First of all, the book focuses first on explaining SQL language as a Standard, as it is formalized in several revisions through the years.
Second, probably to cover some deficiency of the earlier editions, the author spent some time explaining how different commercial versions of SQL differ slightly in their implementation. New sections were added in this 6th edition to highlight the way mySQL, Oracle SQL and other dialects implement certain constructs through slight language changes.
Last but not least - as the title reads - this is a book on Database "CONCEPTS" which means that its describes (and very well indeed) the concepts behind the definition of a DBMS and it does it from both a theoretical and practical standpoint.
The perfect fruition of this book comes from its study side by side with practical assignments on some implementation of SQL. Since the book focuses on SQL Standard, rather than sticking with one specific implementation, the savvy student should acquaint oneself with the Reference Guide of the SQL implementation of his/her (or the teacher's) choice, and get to study on an actual database system.
What I think is missing is an appendix to collect into a single place some BNF charts of the most common implementations, or a table to quickly lookup the differences among these dialects of SQL, so that the students can get an initial reference to jump start into using some DBMS in practice.
One last important thing: this book exists in two versions. The hardcover is considerably more expensive than the paperback, but the quality of the paper, the ink and the fonts used make a big difference in the fruition of the book. Their ISBNs differ. Beware that there are many resellers that ship the paperback after receiving an order for a hardcover. These resellers try to get away with the excuse that the text is the same between versions. Indeed, if economy is more important to you than the quality of the print, then the paperback is a good way to save money, because there is a big difference in value between the two ISBNs.
But if you pay the price for hardcover and get a paperback they you have been the victim of a "bait-n-switch" fraud. I was one of those victims, so I reported the reseller to Amazon, which forced that reseller to pay a refund.
For example, chapter eight covers relational database design. It’s a relatively straight-forward topic about functional dependencies and the authors choose to combine definition and example with use mathematics equations, abstract variables instead of easy to follow English. A topic which should be a fast read becomes a tedious endeavor. The omission of clear explainations for every mathematic formula plagues much of computer science writing and this text makes little effort to inoculate it’s readers from its ravaging effects. Perhaps in the next edition, the authors will choose to include the name, pronunciation, and meaning for each symbol used. Small efforts like this allow readers to flow through a chapter’s concepts without becoming tripped up at each formula. Then after understanding the ideas, the reader can go back and study the formula in greater detail.
Combine the above with the generally obtuse sentence structures this text sucks the life out of the subject matter which is a shame because the University dataset it uses in appendix A has so much potential. Take for example, “It turns out that, this algorithm may take an amount of time quadratic in the size of F.” A simple rewording of this sentence and others would speed up the amount of time you spend reading each chapter.
The only good parts of this text are the truly “advanced” topics but it’s a shame this text chooses to pad its contents with an obfuscated rehashing of the more elementary database concepts. The hardback version is a good quality and the paper and ink are smooth and clear. I also like the way it highlights key terms in blue.
If you're taking a databases class and are struggling, this is a good and cheap book to cross reference with professor lectures and required text readings.
