Data Definition Language (DDL)

Maintain the structure of the data and the metadata. These statements are CREATE, ALTER, and DROP.

Data Manipulation Language (DML)

Maintain the structure of the data. These statements are INSERT, UPDATE, DELETE.

Data Control Language (DCL)

Protect the database, including the data. These statements are COMMIT, ROLLBACK, GRANT, and REVOKE.

See "SQL-92 Statements," for more information on these statements.
