Which of the following is not one of the Codd's rules ?
Answer: C
The one that is not a Codd rule is The structure definition stored in data dictionary should be accessible to all users.
Codd's rule 4 (dynamic online catalogue) requires the database's description to be stored like ordinary data and to be queryable by authorised users with the same relational language, not by all users.
The other options paraphrase real rules: the information rule (all data in tables), rule 3 (systematic treatment of nulls) and rule 7 (high-level insert, update and delete of sets of rows as well as single rows).
