First,Second,Third Normal Forms, Dependency P

Description 1NF A relation is in 1NF if it contains an atomic value. 2NF A relation will be in 2NF if it is in 1NF and all non-key attributes are fully functional dependent on the primary key. 3NF A relation will be in 3NF if it is in 2NF and no transition dependency exists. BCNF A stronger definition of 3NF is known as Boyce Codd's normal form. 4NF A relation will be in 4NF if it is in Boyce Codd's normal form and has no multi-valued dependency. 5NF A relation is in 5NF. If it is in 4NF and does not contain any join dependency, joining should be lossless.
