Third normal form (3NF) is a database schema design approach for relational databases which uses normalizing principles to reduce the duplication of data...

Second normal form (2NF), in database normalization, is a normal form that is met if each attribute that is not part of the primary key depends on all...

First normal form (1NF) is a property of a relation in a relational database. A relation is in first normal form if and only if no attribute domain has...

Boyce–Codd normal form (BCNF or 3.5NF) is a normal form used in database normalization. It is a slightly stricter version of the third normal form (3NF)....

Elementary key normal form (EKNF) is a subtle enhancement on third normal form, thus EKNF tables are in 3NF by definition. This happens when there is...
