title: Is this in BCNF, 3NF or neither?
body: <p>My doubt is for a given set of funtional dependencies F = { AE -> BCD, B -> E 
  }. Is this in BCNF or 3NF? It's a question from a test I have recently done and I would say that it is 3NF, but my teacher said it's neither 3NF nor BCNF. (I believe it is an error).</p>
  
  <p>I have obtained as candidate keys AE and AB, and as in the first functional dependency the left side is a candidate key and in B -> E, E is contained in a candidate key, so it is in 3NF.</p>
  
  <p>Is this in BCNF,  3NF or neither?</p>
