ABSTRACT. 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.
Database Management Systems, R. Ramakrishnan. 2. Tuning the Conceptual Schema y The choice of conceptual schema should be guided by the workload, in addition to redundancy issues: – We may settle for a 3NF schema rather than BCNF. – Workload may influence the choice we make in decomposing a relation into
decisions, and to refine the conceptual and external schemas (if necessary) to meet performance goals. ? We must begin by understanding the workload: ? The most important queries and how often they arise. ? The most important updates and how often they arise. ? The desired performance for these queries and updates.
Database tuning describes a group of activities used to optimize and homogenize the performance of a database. It usually overlaps with query tuning, but refers to design of the database files, selection of the database management system (DBMS) application, and configuration of the database's environment (operating
