Answer 1

DML is Data Manipulation Language : it is used to manipulate data itself. For example, with SQL, it would be instructions such as insert , update , delete

DDL is short name of Data Definition Language, which deals with database schemas and descriptions, of how the data should reside in the database.

Answer 2

The SQL statements that are in the DML class are INSERT, UPDATE and DELETE. Some people also lump the SELECT statement in the DML classification. Data Definition Languages (DDL) are used to define the database structure. Any CREATE, DROP and ALTER commands are examples of DDL SQL statements
