Your database's design also plays an important role in performance. In this article, I'll discuss some of the things you can do to improve your SQL Server database's performance. I'll also discuss how you can make sure your queries are taking full advantage of indexes and statistical information. You should take performance into account from the beginning of your database's design phase. However, you can make modifications after your database goes into production that affect performance greatly.
Indexes are database objects that optimize the searching and sorting of data.
Properly configured indexes can make a huge difference in the time it takes to get data out of or insert data into your database. The ITW can aid you in determining how you should implement indexes in your database for maximum performance gain. You can use the ITW to recommend the best configuration of indexes for a database based on a given workload. A workload is a SQL script or trace that you save to an external file. The ITW's recommendations are only as good as the workload, so it's important that you prepare the proper information first.
