There is one universal database constant: No matter what, your database will change over time.
Service level agreements (SLAs) and user expectations, on the other hand, remain mostly the same: Application performance will not degrade significantly. Unfortunately, most tools are insufficient to enable database administrators (DBAs) to manage change and maintain database performance. Quest has a tool that can help — Benchmark Factory® for Databases, which enables DBAs to capture and replay live database workloads before and after database changes and scientifically determine whether the change is positive or negative.
