Do you think BCNF is better than 2NF & 3NF? Why?

Question

Accepted Answer

BCNF is not necessarily better than 2NF & 3NF, it depends on the specific requirements of the database.

BCNF is the highest normal form and ensures that there are no non-trivial functional dependencies between any subset of candidate keys.
2NF and 3NF are also important and should be used when appropriate.
For example, if a database has a composite primary key and non-key attributes that depend on only one part of the key, 2NF should be used.
If a database has transitive dependencies between non-key attributes, 3NF should be used.
However, if a database has multiple candidate keys and non-trivial functional dependencies between them, BCNF should be used.
Ultimately, the choice of normal form depends on the specific requirements and constraints of the database.

Accepted Answer

BCNF is a stronger form of normalization than 3NF because it eliminates the second condition for 3NF, which allowed the right side of the FD to be a prime attribute. Thus, every left side of an FD in a table must be a superkey.
