Question
Compared to 3NF, BCNF eliminates more redundancy.Question 3Select one:TrueFalse
Solution
True.
BCNF (Boyce-Codd Normal Form) is a stricter standard than 3NF (Third Normal Form). It is designed to reduce redundancy in relational databases. BCNF eliminates more redundancy than 3NF by ensuring that every non-trivial functional dependency in the database schema is a dependency on a superkey. This means that BCNF can handle situations that 3NF cannot, thus eliminating more redundancy.
