Answer 1

Answer:

Every non-key attribute depends on the key (1st normal form) the whole key (2nd normal form) and nothing but the key (3rd normal form) so help me Codd. ... A relation is in third normal form if it is in 2NF and there are no dependencies between non-key attributes. (i.e. 2NF + no transitive dependencies).
