I have the relation (A,B,C,D,E).
The relevant functional dependencies are:
- { E,B,C } → { D }
- { A,B } → { C }
- { E,B,D } → { C }
- { E,A,B } → { D }
The candidate key is (E,A,B).
I do not understand why this relation is not in BCNF, because the candidate key and its attributes are only elements on the left. Thanks a lot for any help!
