Now a day most of the applications deal with large volume of data. Unfortunately, database tuning has become one of the complex and challenging task of the application development. A single small mistake can degrade the database performance up to 90%!! A database developer has a lot of confusion regarding which one is the best approach. One of the root cause of the complexity of database tuning is query processing is very much hidden. Here our goal is to explain the complex query tuning process in very simple way that every one can understand it easily.
