What is Query Optimization?
Query optimization is the process of selecting the most efficient way to execute a SQL query. It involves analyzing different possible execution plans and choosing the one that minimizes resource consumption (CPU, memory, I/O) and execution time. Database management systems (DBMS) use query optimizers to automatically perform this process. Common optimization techniques include index usage, join order optimization, and subquery optimization.
