Question
Choose the incorrect statement:Select one:a.A relation in BCNF must also be in 3NFb.A relation in 3NF must also be in 2NFc.A relation in 3NF must also be in BCNFd.A relation in 2NF must also be in 1NF
Solution
The incorrect statement is:
c. A relation in 3NF must also be in BCNF
Explanation:
BCNF (Boyce-Codd Normal Form) is a stricter standard than 3NF (Third Normal Form). While it's true that a relation in BCNF is also in 3NF, the reverse is not necessarily true. A relation can be in 3NF without meeting the requirements for BCNF. Therefore, statement c is incorrect.
