Description
What can you do when database performance doesn't meet expectations? This book offers methods for refactoring (or changing) SQL code to improve performance without altering a database application's purpose -- and helps you do it on a shoestring budget. This isn't a rehash of theory, but a tested set of options for making code modifications to dramatically improve the way your applications function.

About the Authors

  1. Stephane Faroult

    Stephane Faroult first discovered relational databases and the SQL language back in 1983. He joined Oracle France in their early days (after a brief spell with IBM and a bout of teaching at the University of Ottawa) and soon developed an interest in performance and tuning topics. After leaving Oracle in 1988, he briefly tried to reform and did a bit of operational research, but after one year, he succumbed again to relational databases. He has been continuously performing database consultancy since then, and founded RoughSea Ltd in 1998.

  2. Pascal L'Hermite

    Pascal L'Hermite has been working with relational databases in OLTP, production and development environments on Oracle Databases for the past 12 years and on Microsoft SQL Server for the past 5 years.
