For over 25 years, C. J. Date's 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 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..

I am still reading this book. But I can tell that is the most important book for any developer out there. Read it. Watch the videos.

Really enjoyed it, it was surprisingly easy to read. Explained all the rules and principles well. I was thinking about our production code all the time while reading it.

Very good book. I lerant a lot from this book.

Date's seminal work is critical to understanding databases - a step mostly forgotten by those who believe every concept can be taught using commercial products with brain-dead examples in under 24 hours. Date teaches the logic and theory that underlie all successful practice. You can probably buy a different book and create a mock database faster, but you will neither understand nor be able to use it well. Do yourself a favor and read this first to understand what a database is; only then can you judge the value of other books.

Just THE most important book about databases and especially Reational databases. If you need to know anything about the subject its here.

I was lucky enough also to meet CJ Date and he is a very knowlegable and friendly person who well deserves the admiration of his readers.

A rigorous, highly opinionated overview of database theory and some practice. Transaction management is only lightly covered but the sections on relational algebra/calculus and normalization make up for it.

[Federico Razzoli · Rating 4 out of 5]

A wonderful book from an academic point of view. It is mostly easy to read, yet it provides a solid knowledge about the theory that is behind relational databases. The book's approach is progressive: first it explains things in a more understandable way and then, when the reader has enough information, it proceeds to more formally correct explanations.

Unfortunately, the author's approach is a bit too theory-centric. He strongly criticises "inconsistencies" between the math and existing systems. This is a point of views that must be respected of course, but sometimes he doesn't see that these inconsistencies make them fast and able to scale as required by modern workloads.

This book is very comprehensive and theoretical description of relational databases, but this is it's bad side. High theoretical level and lack of real-world examples can't make it, for example, be recommended as an introduction as said in it's title

[Ling Wang · Rating 3 out of 5]

本是一本好书，但是作者为苛求严谨而描述的过于细致，以至于有罗唆之感。
如果精炼一把，页数估计能减半，那时我给4星；但是现在我只想给2.5星。
不过也有章节确实因为本书特有的严谨细致把问题解释的特别清晰的，如 Chapter 15、16、20。尤其是 Chapter 20，对 Type Inheritance 给出了逻辑性极强，极其缜密的辨析，让我跳出通俗传统的 OO 理论，对 Type(Class) 有了更全面的理解。
正是由于这几章挽回了我的些许好感，暂时打3星吧.

[Graham Lee]

Definitely comprehensive. I find it an amusing indictment of the industry (though not of this book) that SQL doesn't implement the relational model, and the relational DBMSs don't implement standard SQL.

Wonderful book. This book significantly improved my database skills when I was starting out as a relatively new programmer. (New meaning Delphi programmer, who finally earned access to full data rights to our Oracle databases.)

This was a text I used in my college DB course - had to use it for review again recently - it's been a decent go-to book for a DB refresher.

[Ivan · Rating 4 out of 5]

Классическая книга по базам данным. Ничего принципиально нового, зато старое отлично раскладывается по полочкам.

The seminal first year text on database structures and systems. This one influenced me quite a lot.
