  • Morgan Helms thinks this is interesting:

SQL has several categories of statements, including Data Definition Language (DDL), Data Manipulation Language (DML), and Data Control Language (DCL). DDL deals with object definitions and includes statements such as CREATE, ALTER, and DROP. DML allows you to query and modify data and includes statements such as SELECT, INSERT, UPDATE, DELETE, TRUNCATE, and MERGE.
