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.

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. green bay packers ir list https://checkpointplans.com
