DML stand for (Data Manipulation Language ) and it is backbone of any database query which have some commands to permitting users to manipulate data in a database. That manipulation involves inserting data into database tables, retrieving existing data, deleting data from existing tables and modifying existing data. DML is mostly incorporated in SQL databases. The main functional of DML is SELECT, UPDATE, INSERT INTO and DELETE FROM the database. There are two types of DML which are both important to the database first one is procedural in which the user specifies what data is needed and how to get it and second nonprocedural in which the user specifies only what data is needed.
