Question: Consider the relation: R(A, B, C, D, E, F, G, H, I, J, K, L,M,N,O,P,Q), {A, B} is the primary key, {C,D,E} forms a candidate key. The following functional dependencies exist among the attributes of the relation: {A} -> {F,G}; {C,D} -> {H,I}; {F} -> {J,K}; {I} -> {L,M}; {M} -> {N,O,P}    Transform this relation into 2NF, then 3NF relations.

Question:

Consider the relation: R(A, B, C, D, E, F, G, H, I, J, K, L,M,N,O,P,Q),

{A, B} is the primary key,

{C,D,E} forms a candidate key. The following functional dependencies exist among the attributes of the relation:

{A} -> {F,G};

{C,D} -> {H,I};

{F} -> {J,K};

{I} -> {L,M};

{M} -> {N,O,P}   

Transform this relation into 2NF, then 3NF relations.
