What can DDL be used for? (Choose three.) A Add columns to a database table C Add data to a database table Add privileges for a user to a database table Add comments to a database table

DDL, or Data Definition Language, is primarily used for defining and managing all aspects of a database's structure. For instance, it allows you to add columns to a database table using the ALTER TABLE command, enabling the table to evolve as your data needs grow. Moreover, DDL can also be used to add comments to a database table, providing context and documentation within the database to help users understand the purpose of individual tables or columns better. As for real-world applications, think of DDL as the architect of a building—laying down the foundations and frameworks that everything else is built upon. For instance, when a company needs to expand and collect more data, DDL commands will efficiently modify the schema, ensuring the database remains robust and relevant to the ever-changing business landscape!
