||A relation is in 1NF if it contains an atomic value.
||A relation will be in 2NF if it is in 1NF and all non-key attributes are fully functional dependent on the primary key.
||A relation will be in 3NF if it is in 2NF and no transition dependency exists.
||A relation will be in 4NF if it is in Boyce Codd normal form and has no multi-valued dependency.
||A relation is in 5NF if it is in 4NF and not contains any join dependency and joining should be lossless.
