Other normalization forms Fourth normal form, also called Boyce-Codd Normal Form (BCNF), and fifth normal form do exist, but are rarely considered in practical design. Disregarding these rules may result in less than perfect database design, but shouldn't affect functionality. Normalizing an examp...
