DDL (Data Definition Language)

Data Definition Language (DDL) refers to a group of commands used in databases to define and manage the structure of data. It allows you to create, modify, or delete database objects like tables, indexes, and schemas. Common DDL commands include CREATE (to build new structures), ALTER (to change existing ones), and DROP (to remove them). Essentially, DDL is about organizing how data is stored, ensuring that information is structured efficiently for use when needed.
