A. First normal form B. Second normal form C. Third form D. Fourth normal form
Explanation: Third normal form (3NF) relaxes this constraint slightly by allowing certain nontrivial functionaldependencieswhose left side is not a superkey. 7. If an attribute of a composite key is dependent on an attribute of the other composite key, a normalization called _____ is needed.
