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

Consider the relation R={A,B,C,D,E,F,G,H,I,J} and 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 2NF and then 3 NF Relations. Hint: The key attribute for a relation is the attribute(s) that can determine all of the other attribute values.
