WebAug 25, 2024 · A full functional dependency is a state of database normalization that equates to the normalization standard of Second Normal Form (2NF). In brief, this means that it meets the requirements of First Normal Form (1NF), and all non-key attributes are fully functionally dependent on the primary key. This is not as complicated as it may sound. Web2nd Normal Form With Example : The data is said to be in 2NF If, 1.It is in First normal form. 2.There should not be any partial dependency of any …
