title: Maximal Number of Functional Dependencies (including trivial)
body: <p>In a relationship R of N attributes how many functional dependencies are there (including trivial)?</p>
  
  <p>I know that trivial dependencies are those where the right hand side is a subset of the left hand side but I'm not sure how to calculate the upper bound on the dependencies.</p>
  
  <p>Any information regarding the answer and the approach to it would be greatly appreciated.</p>
