Data Definition Language

Data Definition Language (DDL) is a part of a database management system that helps users define and manage the structure of a database. It includes commands that allow you to create, alter, and delete database objects like tables and indexes. For example, with DDL, you can set up a table to store customer information, specifying what data types (like text or numbers) each column will hold. DDL ensures that the database is organized and ensures data integrity, making it easier to store and retrieve information effectively.
