Discussion
A relation is in ______ if an attribute of a composite key is dependent on an attribute of another composite key.
Answer: B
Correct answer: 3NF
This is the transitive dependency that third normal form forbids: a non-key attribute determining another non-key attribute. Second normal form removes only partial dependencies on part of a composite key, so the relation can satisfy 2NF and still fail here.
