      What does BCNF stand for?
      Boyce–Codd normal form (BCNF or 3.5NF) is a normal form used in database normalization. It is a slightly stricter version of the third normal form (3NF). By using BCNF, a database will remove all redundancies based on functional dependencies.

      What is BCNF in DBMS?
      BCNF (Boyce-Codd Normal Form) in DBMS, introduced by R.F. Boyce and E.F. Codd in the 1970s, is a normalization technique that eliminates table redundancy and anomalies for enhanced data integrity. While 2NF and 3NF address certain dependencies, BCNF addresses additional constraints that can persist, causing redundancy even in 3NF relations.

      What is BCNF in database normalization?
      BCNF BCNF is a more advanced stage of database normalization. It builds upon the principles of 3NF. BCNF further eliminates redundancies and dependencies to ensure data consistency and integrity. A relation (table) is said to be in BCNF if, and only if, for every functional dependency X → Y, X is a superkey.

      Why do we use BCNF?
      By using BCNF, a database will remove all redundancies based on functional dependencies. Edgar F. Codd released his original article "A Relational Model of Data for Large Shared Databanks" in June 1970. This was the first time the notion of a relational database was published.

      What is BCNF based on?
      To deal with such situations, BCNF was introduced. BCNF is based on functional dependencies, and all the candidate keys of the relation are taken into consideration.
