A database is in third normal form if it satisfies the following conditions: It is in second normal form; There is no transitive functional dependency; By transitive functional dependency, we … Third normal form (3NF) is a database schema design approach for relational databases which 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 … See more The third normal form (3NF) is a normal form used in database normalization. 3NF was originally defined by E. F. Codd in 1971. Codd's definition states that a table is in 3NF See more The definition of 3NF offered by Carlo Zaniolo in 1982, and given above, is proven in the following way: Let X → A be a nontrivial FD (i.e. one where X does not contain A) and let A be a non-key attribute. Also let Y be a key of R. Then Y → X. See more While 3NF was ideal for machine processing, the segmented nature of the data model can be difficult to consume by a human user.
