SQL Tuning

SQL tuning is the process of improving the efficiency and speed of database queries (commands that retrieve or manipulate data). When a query runs slowly, tuning involves analyzing and optimizing it—such as restructuring the query, creating or adjusting indexes, or modifying database settings—to reduce the time and resources needed. This makes data retrieval faster and more efficient, ensuring that applications relying on the database perform smoothly and responsively. Essentially, SQL tuning is about refining queries to work smarter, not harder, for better overall system performance.
