商品描述

All of today’s mainstream database products support the SQL language, and relational theory is what SQL is supposed to be based on. But are those products truly relational? Sadly, the answer is no. This book shows you what a real relational product would be like, and how and why it would be so much better than what’s currently available.

With this unique book, you will:

  • Learn how to see database systems as programming systems
  • Get a careful, precise, and detailed definition of the relational model
  • Explore a detailed analysis of SQL from a relational point of view

There are literally hundreds of books on relational theory or the SQL language or both. But this one is different. First, nobody is more qualified than Chris Date to write such a book. He and Ted Codd, inventor of the relational model, were colleagues for many years, and Chris’s involvement with the technology goes back to the time of Codd’s first papers in 1969 and 1970. Second, most books try to use SQL as a vehicle for teaching relational theory, but this book deliberately takes the opposite approach. Its primary aim is to teach relational theory as such. Then it uses that theory as a vehicle for teaching SQL, showing in particular how that theory can help with the practical problem of using SQL correctly and productively.

Any computer professional who wants to understand what relational systems are all about can benefit from this book. No prior knowledge of databases is assumed.

商品描述(中文翻譯)

今天的主流資料庫產品都支援SQL語言,而SQL應該是基於關聯理論的。但這些產品真的是關聯的嗎?可惜的是,答案是否定的。這本書將向您展示真正的關聯產品應該是什麼樣子,以及為什麼它們比目前的產品更好。

這本獨特的書籍將使您能夠:
- 學習將資料庫系統視為程式設計系統
- 獲得對關聯模型的仔細、精確和詳細的定義
- 從關聯的角度詳細分析SQL

有數百本關於關聯理論或SQL語言的書籍,但這本書與眾不同。首先,沒有人比Chris Date更適合寫這樣一本書。他和關聯模型的發明者Ted Codd多年來一直是同事,Chris對這項技術的參與可以追溯到Codd在1969年和1970年發表第一篇論文的時候。其次,大多數書籍試圖使用SQL作為教授關聯理論的工具,但這本書故意採取相反的方法。它的主要目的是教授關聯理論本身,然後將該理論作為教授SQL的工具,特別是展示該理論如何幫助正確且有效地使用SQL解決實際問題。

任何想要了解關聯系統的計算機專業人士都可以從這本書中受益。不需要先備的資料庫知識。
