Technical Background
SQL (Structured Query Language) is the standard query language for relational databases, standardized by ANSI/ISO. It's divided into DDL (CREATE/ALTER/DROP), DML (SELECT/INSERT/UPDATE/DELETE), and DCL (GRANT/REVOKE). Understanding SQL execution order (FROM→WHERE→GROUP BY→HAVING→SELECT→ORDER BY→LIMIT) is crucial for query optimization.
