Question
Choose the correct answerWhich one of the following statements about normal forms is FALSE?OptionsBCNF is stricter than 3 NFLossless, dependency–preserving decomposition into BCNF is always possibleAny relation with two attributes is BCNFLossless, dependency-preserving decomposition into 3 NF is always possible
Solution
The false statement is: "Lossless, dependency–preserving decomposition into BCNF is always possible."
This is because, while it's always possible to decompose a relation into BCNF in a lossless manner, it's not always possible to preserve dependencies. This is a key difference between BCNF and 3NF. In 3NF, we can always achieve a lossless, dependency-preserving decomposition.
