Explanation

SQL is commonly categorized into 4 main types: DDL (Data Definition Language) for schema operations, DML (Data Manipulation Language) for data operations, DCL (Data Control Language) for permissions, and TCL (Transaction Control Language) for transaction management. Some classifications may include DQL separately, but 4 is the standard answer.
