Boyce-Codd Normal Form (BCNF)

Boyce-Codd Normal Form (BCNF) is a way to organize database data to eliminate redundancy and prevent inconsistencies. It ensures that every piece of information depends solely on the main key (a unique identifier for each record). In simplified terms, BCNF requires that no non-key attribute (a piece of information that isn't part of the key) should determine another non-key attribute. By doing so, it helps maintain data accuracy, reduces duplication, and makes updating and maintaining the database more reliable and efficient.
