Consider the universal relation R = (A, B, C, D, E,

Consider the universal relation R = (A, B, C, D, E, F, G, H, I, J and the set of functional dependencies F = {{A, B} -- {C}, {B, D} - {E,F), (AD)-(GH) (A) -- {0}, {H} - {J}} What is the key for R? Is this relation Risin 2NF? Justify your answer and decompose if necessary. Then argue whether further normalization to 3NF is necessary, and it so rform it. rm your second device
