Description: SQL query optimization in PostgreSQL refers to a set of techniques and strategies designed to improve the performance of queries executed on relational databases. This involves analyzing and adjusting the way queries are structured, as well as how data is accessed. Optimization is crucial to ensure that applications relying on the database operate efficiently, especially when handling large volumes of data. Common techniques include the use of indexes, rewriting queries to avoid costly operations, and utilizing performance analysis tools like PostgreSQL’s query planner. Optimization not only enhances query speed but also reduces server load, which can lead to better resource utilization and a smoother user experience. In a business environment, where response time is critical, query optimization becomes an essential practice to maintain competitiveness and customer satisfaction.
