Full Dependency

A dependency is said to be full if and only if the determinant of the dependency is either a candidate key or a super key.

Note: Dependent of the full dependency can be either prime or non prime attribute.

X -> Y

  • X is either candidate key or super key
  • Y could be any attribute Prime or Non Prime.

Note: Full Dependency will always cause Zero % redundancy hence we need not to eliminate full dependency.
