Question: (FDs) Consider relation R(A,B,C,D,E) with functional dependencies AB->C, BC->D, CD->E, DE->A, and AE->B. Which FDs hold on the projected relation S(A,B,C,D)? To answer this question,
(FDs) Consider relation R(A,B,C,D,E) with functional dependencies AB->C, BC->D, CD->E, DE->A, and AE->B. Which FDs hold on the projected relation S(A,B,C,D)? To answer this question, you will need to first derive all the FDs that follow from the given ones and then restrict to those that involve only the attributes in the projected relation. Explain your answers in detail.
