A database book that is very comprehensive and still can be used by beginners to understand the principle concepts of database engineering.
It was especially recommended by our university professor who called one of the authors, Mr. Ullman, an authoriy on the subject.
The only thing which I didn't like about it is the fact that the solutions to the exercises are not included in the book. Some of them can be found on the website of the book, but not all of them...

It is really a complete DB book. This book sistematically gives an overall vision of databases world. At the beginning it explains database systems at the high level introducing different models like relational, object, XML and others. Relational Algebra and query languages are discussed in understandable manner. It continues with system aspects, architecture and implementation.
I found it very readable and helpful. Presented topics are enriched with examples. At the end of each chapter there are some exercises, unfortunately only for some of them there are solutions available on the WEB.
