- Based on concept of transitive dependency:
– A, B and C are attributes of a relation such that if A –> B and B –> C,
– then C is transitively dependent on A through B. (Provided that A is not functionally dependent on B or C).
- 3NF – A relation that is in 1NF and 2NF and in which no non-prime attribute is transitively dependent on the primary key.
