For over 25 years, C. J. Dates An Introduction to Database Systems has been the authoritative resource for readers interested in gaining insight into and understanding of the principles of database systems. This exciting revision continues to provide a solid grounding in the foundations of database technology and to provide some ideas as to how the field is likely to develop in the future. The material is organized into six major parts. Part I provides a broad introduction to the concepts of database systems in general and relational systems in particular. Part II consists of a careful description of the relational model, which is the theoretical foundation for the database field as a whole. Part III discusses the general theory of database design. Part IV is concerned with transaction management. Part V shows how relational concepts are relevant to a variety of further aspects of database technology-security, distributed databases, temporal data, decision support, and so on. Finally, Part VI describes the impact of object technology on database systems. This Seventh Edition of An Introduction to Database Systems features widely rewritten material to improve and amplify treatment of several topics, including: *Revised and expanded material on the relational model, particularly the sections on types (domains), relation values vs. relation variables, integrity, predicates, and views * New material on relation-valued attributes, denormalization, orthogonal design, and alternative approaches to semantic modeling (including "business rules") * Complete new chapters covering type inheritance, decision support, and temporal databases * Two new appendixes, one on detail of SQL and one on SQL3 Readers of this book will gain a strong working knowledge of the overall structure, concepts, and objectives of database systems and will become familiar with the theoretical principles underlying the construction of such systems. 0201385902B04062001

5.0 out of 5 stars Best database book., 21 Jun 2007

By	A. J. HAWKEN "Tony Hawken" (London - UK) - See all my reviews (REAL NAME)

I first came across this book on my MSc course. Here I was using the third and fourth editions. They even use this book in China. I taught from the fourth edition in 1996. The seventh edition contains much of the material in earlier editions but has been refined and updated.

It is remarkable how such an authorative and comprehensive book can be so clear and accessible. Nevertheless it cannot be described as an easy read because of the size. It will take many months to read this book, but the effort should be worthwhile.

... If you are a computing Student and have great interest in Database. This is the ideal book to help you understand database system better. The book is very easy to understand and easy to follow. Try it and you are not going to be disappointed. I used the book for my database project and I have a better knowledge on the field.

5.0 out of 5 stars The surest way to grow is to have solid foundations!, 22 April 2002

By	av1@btinternet.com (UK) - See all my reviews

If you are looking for a quick 'how to' approach to developing a database look elsewhere.
If however you are looking for a sound introduction to the fundamentals written clearly in a reasoned and logical style then this should be the No 1 choice.
Its like an old friend that you can rely on to steer you in the right direction, making sure you get things right from the start and are not wasting time making modifications or enhancements that should have been implemented by a better understanding from the outset!

4.0 out of 5 stars Excellent content, shame about the style
If you are interested in database theory, then this is a great book. If I were rating this book purely on the information it contained, I should award it five stars. Read more
