What are DDL and DML?

Answer

The Data Definition Language (DDL) part of SQL permits the creation or deletion of database tables. It also defines indices (keys), specifies links between tables, and imposes constraints on tables. DDL contains necessary statements for creating, manipulating, altering, and deleting tables. Data Manipulation Language (DML) is a part of SQL that helps users manipulate data. It contains necessary statements for inserting, updating, and deleting data.
