If the data has no partial dependencies, repeating groups, or transitive dependencies and has a composite primary key, it is in third normal form (3NF). This means that all non-key attributes are dependent only on the primary key and not on any other non-key attributes. This helps to eliminate redundancy and improve data consistency. First normal form (1NF) deals with atomicity and second normal form (2NF) deals with ensuring that all non-key attributes are fully dependent on the primary key. However, third normal form (3NF) is the highest level of normalization that most databases aim to achieve.
