2NF Normal Form:
A relation schema process R is in 2NF if it is in 1NF and each non-prime attribute A in R is fully functionally related on primary key. Second normal form (2NF) is a normal process needed in database normalization. 2NF was originally described by E.F. Codd in 1971. A table that is in first normal form (1NF) must accept additional criteria if it is to accept for second normal form. A table is in 2NF if and only if, it is in 1NF and no non prime attribute is related on any proper subset of any candidate key of the table.
