Database Benchmarking: Practical Methods for Oracle & SQL Server (資料庫基準測試：Oracle 與 SQL Server 的實用方法)

Description

Every information system must know their limits.  As systems grow, resources are stressed and one of the major causes of unplanned database outages is a failure to anticipate the effects of growth.

Benchmarking is a critical job function and every database professional must understand the principles of capacity planning and database bottleneck analysis.  By using a benchmark method you can spot areas of pending problems before they cripple your database.

This landmark book explores all aspects of database benchmarking and shows you a real-world approach that ensures that you are prepared for whatever the future brings to your mission-critical database.
