What Is Boyce-Codd Normal Form (BCNF)?

The goal of Boyce-Cstrange Normal Form is to surge information integrity depend on organizing the columns as well as tcans of a relational informationbsimilare in order to makeprogress informationbsimilare normalization. Databsimilare normalization happens clues there are start ed relationships between tcans as well as clues the tcans establish tellthedifference d rules to produce the informationbsimilare […]
