Relational Database Index Design and the Optimizers pdf epub mobi 圖書描述

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 Many of the old design recommendations are therefore no longer valid-the optimal point of indexing has come a long way.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.

評分☆☆☆☆☆

《高性能MySQL》索引部分推薦的一本好書，對於想瞭解索引設計與優化的讀者，非常值得一讀。對比與其他數據庫書籍隻是對索引粗略的介紹，本書詳細介紹瞭索引相關的方方麵麵，特彆是通過3 stars， BQ, QUBE等評估方式，通過對random reading, sequence reading和fetch rows...
