Brief introduction about database design & Database normalization basics Relation is in 1NF. Second Normal Form (2NF) According to the E.F. Codd, a relation is in 2NF, if it satisfies the following conditions:. A relation must be in 1NF. And the candidate key in a relation should determine all non-prime attributes or no partial dependency should exist in the relation.

Get all the Normalization process (1NF, 2NF, 3NF, BCNF, 4N and 5NF) in detailed with examples. The basic difference between 3NF and BCNF is that 3NF eliminates the transitive dependency from a relation and a table to be in BCNF, the trivial functional dependency X->Y in a relation must hold, only if X is the super key.. Let us discuss the differences between 3NF and BCNF with the help of comparison chart shown below.
