DDL Interpreters are computer programs designed to process and execute Data Definition Language (DDL) statements. These statements are used to create, modify, and delete database structures such as tables, indexes, and constraints. DDL Interpreters play a crucial role in managing the database schema and ensuring data integrity.

The basic difference between DDL and DML is the commands they provide . The DDL provides statement for the creation and deletion of tables, indexes, views etc. while the DML provides statements to enter, update, delete and perform complex queries on these tables.
