評分簡單estimation比較實用。細節的地方不容易看懂。如果有事例庫和腳本就好瞭。

評分很老的一本書, 翻譯成中文版後纔知道; 其實另外還有一個途徑可以知道, 這本書在<high performance MySQL>的引用裏頭. 書太老瞭,裏麵沒有什麼有參考性的東西。幸虧用中文版翻瞭翻,否則時間損失更大瞭

Tapio Lahdenmaki,數據庫性能顧問,教授通用索引設計課程。他在IBM公司工作瞭三十多年,是公司全球課程中有關DB2 (for z/OS)性能相關課程的主要作者。Michael Leach,關係型數據庫顧問,已從IBM公司退休,他擁有二十年的應用係統及數據庫課程的教授經驗。兩位作者的文章均被翻譯成瞭多國語言廣為傳播。他們有關索引設計的方法被成功應用於許多核心係統。
Improve the performance of relational databases with indexes designed for today's hardware
Over the last few years, hardware and software have advanced beyond all recognition, so it's hardly surprising that relational database performance now receives much less attention. Unfortunately, the reality is that the improved hardware hasn't kept pace with the ever-increasing quantity of data processed today. Although disk packing densities have increased enormously, making storage costs extremely low and sequential read very fast, random reads are still painfully slow. Many of the old design recommendations are therefore no longer valid-the optimal point of indexing has come a long way. Consequently many of the old problems haven't actually gone away-they have simply changed their appearance.
This book provides an easy but effective approach to the design of indexes and tables. Using lots of examples and case studies, the authors describe how the DB2, Oracle, and SQL Server optimizers determine how to access data, and how CPU and response times for the resulting access paths can be quickly estimated. This enables comparisons to be made of the various designs, and helps you choose available choices for the most appropriate design.
This book is intended for anyone who wants to understand the issues of SQL performance or how to design tables and indexes effectively. With this title, readers with many years of experience of relational systems will be able to better grasp the implications that have been brought into play by the introduction of new hardware.
An Instructor's Manual presenting detailed solutions to all the problems in the book is available online from the Wiley editorial department.
An Instructor Support FTP site is also available.
《高性能MySQL》索引部分推荐的一本好书, 对于想了解索引设计与优化的读者, 非常值得一读。对比与其他数据库书籍只是对索引粗略的介绍, 本书详细介绍了索引相关的方方面面, 特别是通过3 stars, BQ, QUBE等评估方式,通过对random reading, sequence reading和fetch rows...
