Third normal form (3NF)

Last updated Feb 9, 2024

Third normal form (3NF) is a database schema design approach for relational databases that uses normalizing principles to reduce the duplication of data, avoid data anomalies, ensure referential integrity, and simplify data management.

It was defined in 1971 by Edgar F. Codd, an English computer scientist who invented the relational model for database management.
