Question: Consider the universal relation: R = ( A , B , C , D , E , F , G , H , I, J

Consider the universal relation:
R =(A, B, C, D, E, F, G, H, I, J)
and the set of functional dependencies:
A, B -> C
B, D -> E, F
A, D -> G, H
A -> I
H -> J
What is the key for R? Decompose R into 2NF, and then into 3NF relations (Justify your answer and include all the steps and details).
