Closure of a set of functional dependency
I am little bit confused about the CLOSURE OF A SET-OF-FUNCTIONAL-DEPENDENCIES . If I am given a set of Functional dependencies F, then how the F+ is defined ? Is it defined as the union of the closures of LHS of each of FD within F Or is ... a set of FD's, however, I did not find any procedure to find out the closure of the set of FDs. Thank You
