商品描述

SQL is full of difficulties and traps for the unwary. You can avoid them if you understand relational theory, but only if you know how to put that theory into practice. In this book, Chris Date explains relational theory in depth, and demonstrates through numerous examples and exercises how you can apply it to your use of SQL.

This third edition has been revised, extended, and improved throughout. Topics whose treatment has been expanded include data types and domains, table comparisons, image relations, aggregate operators and summarization, view updating, and subqueries. A special feature of this edition is a new appendix on NoSQL and relational theory.

商品描述(中文翻譯)

SQL充滿了對於不熟悉者來說困難和陷阱。如果你理解關聯理論，你可以避免這些問題，但只有當你知道如何將理論應用於實踐時才能做到。在這本書中，Chris Date深入解釋了關聯理論，並通過眾多的例子和練習展示了如何將其應用於SQL的使用中。

這本第三版在整體上進行了修訂、擴充和改進。擴展處理的主題包括數據類型和域、表比較、圖像關係、聚合運算符和總結、視圖更新和子查詢。這版的一個特點是關於NoSQL和關聯理論的新附錄。
