Trivial Functional Dependency

  • Trivial: If an FD X → Y holds where Y subset of X, then it is called a trivial FD. Trivial FDs are always hold.
  • Non-trivial: If an FD X → Y holds where Y is not subset of X, then it is called non-trivial FD.
  • Completely non-trivial: If an FD X → Y holds where x intersect Y = Φ, is said to be completely non-trivial FD.
