Codd's Twelve Commandments

Codd's Twelve Commandments are guidelines proposed by Dr. E.F. Codd for designing a reliable and effective relational database. They emphasize that data should be stored logically, only once, and be accessible through consistent and simple queries. The commandments promote data independence, meaning users can access data without worrying about how it's stored, and they ensure that the database enforces integrity and correctness. Overall, these principles aim to make databases more flexible, accurate, and easier to manage, supporting reliable data retrieval and updating without unintended errors.
