Multi Valued Dependency
Consider three fields X,Y and Z in a relation. If for each value of X, there is a well defined set of values Y and well defined set of values Z and the set of values of Y is independent of the set of values of Z, then multi valued dependency exists.
A relation is said to be in Fifth NF if it is already in fourth NF and it has no join dependency
