"WebFollowing are the various types of Normal forms: Normal Form. 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. " - Normalization in feature engineering
