| Summary |
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. |
