WebTo solve the question to identify normal form, we must understand its definitions of BCNF, 3 NF, and 2NF: Definition of 2NF: No non-prime attribute should be partially dependent on Candidate Key. i.e. there should not be a partial dependency from X → Y. Definition of 3NF: First, it should be in 2NF and if there exists a non-trivial dependency ... WebDefinition 1. A relation is 3NF if every attribute transitively dependent on a key is a key attribute. Note that inherent in the definition of 3NF is a distinction between key attributes and nonkey attributes. This distinction was removed with the definition of Boyce-Codd Normal Form [lo].
