WebBoyce-Codd Normal form If every Determinant is a candidate key, it is in BCNF. In third normal form, for A->B functional dependency, it allows dependency in the relation if B is a Primary key and A is not a candidate key. But in BCNF, for functional dependency, A must be a candidate key.

A database table is in BCNF if and only if there are no non-trivial functional dependencies of attributes on anything other than a superset of a candidate key. Advertisements BCNF is also sometimes referred to as 3.5NF, or 3.5 Normal Form.

Boyce - Codd normal form (or BCNF or 3.5NF) is a normal form used in database normalization. It is a slightly stronger version of the third normal form (3NF). BCNF was developed in 1974 by Raymond F. Boyce and Edgar F. Codd to address certain types of anomalies not dealt with by 3NF as originally defined. If a relational schema is in BCNF then all redundancy based on functional dependency has been r…
