Q:Question:the set of functional dependencies F={{A, B}?{C},{A}?{D, E},{B}?{F}, {F}?{G, H},{D}?{I, J}}. What is the key for R ? Decompose R into 2 NF and then 3 NF relations. 4.25. Repeat Exercise 14.24 for the following different set of functional dependencies G={{A, B}?{C},{B, D}?{E, F},{A, D}?{G, H},{A}?{I},{H}?{J}}. /r/n Q14.24 Closure (AB)={A, B, C, D, E, F, G, H, I, J} Thus key for the relation R is (AB) The functional dependency A->D, E andA:Answer:See a step by step answer
