Principles of Relational Databases

Following are E.F. Codd’s Twelve Principles of Relational Databases. These principles continue to be the litmus test used to validate the “relational” characteristics of a database product; a database product that does not meet all of these rules is not fully relational. These rules do not apply to applications development, but they do determine whether the database engine itself can be considered truly “relational.” Currently, most RDBMSs pass Codd’s test, including all of the databases discussed in this book, except MySQL. (MySQL does not currently support views or atomic transactions. Therefore, it does not qualify as a true relational DBMS under Codd’s rules.)
