Computer Science & Information Technology
Let X , Y , S, R be sets of attributes such that S ? R and X ? Y = R. Let r be a relation over R that satis?es the nontrivial MVD R = X Y (i.e., neither set X or Y is a subset of the other).
a. Prove that if X ? Y ? S , then the relation ?S(r) satis?es the MVD S =(S ? X) (S ? Y ). b. Suppose X , Y , S ,andR satisfy all the above conditions, except that X ? Y ? S. Give an example of r that satis?es R = X Y but does not satisfy S =(S ? X ) (S ? Y ).
