https://doi.org/10.1007/978-1-4899-6086-3Like anything in life, indexes require maintenance. Over time, the performance benefits of indexes can wane or, through data modifications, their sizes and the underlying statistics can drift and bloat. To prevent these issues, indexes must be maintained. Doing so will help ensure that a database will remain a lean, mean query-running machine!

https://doi.org/10.1007/978-3-662-67504-5In principle, there are only a few things you have to get right to create an efficient application: get the data in the right place, create high-precision access paths for the important user functions, and make sure that you don’t introduce mechanisms that waste resources or cause contention between competing processes.

The Long Haul From Novice to Expert,What is the first thing you think of when you see the topic “Managing SQL Performance”? Do you think of response time? Do you think of user complaints about the application running “too slow”? Do you think of AWR or ADDM reports?
