Performance tuning in database management system means enhancing the performance of database, i.e. minimizing the response time at a very optimum cost. Query optimization is one of the important aspects of performance tuning. Lots of research work has been done in this field but it is still ongoing process. To achieve high performance at a very low cost identification of KPIs (Key Performance Indicators) is necessary, so that by altering these parameters dynamically minimum response time with optimum value can be achieved.
