Abstract	Efficient data retrieval is crucial for database-driven applications due to the rapid expansion of data in modern information systems. The typical way to manage and change relational databases is with SQL. But if SQL queries aren't written correctly, they might take longer to run, require a lot of CPU power, and waste valuable resources. Optimizing SQL queries makes databases work more efficiently by changing slow queries into faster execution plans. A study on SQL query optimization techniques aims to improve query execution performance in relational database systems. The study examines query optimization techniques, including indexing strategies, query rewriting, join optimization, execution plan analysis, and cost-based optimization. Also, real examples show how optimized searches considerably reduce execution time compared to non-optimized queries. Effective optimization strategies can significantly enhance database efficiency and reduce query latency, based on experiments.
Keywords	SQL, Query Optimization, Database Systems, Indexing, Execution Plan, and Database Performance.
