Database Tuning is the process of optimizing a database's performance to ensure efficient data retrieval and storage. This involves adjusting various parameters, such as memory allocation, indexing strategies, and query optimization, to enhance the speed and efficiency of database operations. Effective Database Tuning can lead to faster response times for users and reduced load on server resources. It often includes monitoring performance metrics, analyzing query execution plans, and making necessary adjustments to improve overall system performance and reliability.
