我有一个满足以下关系的表:
R(A, B, C, D, E, F, G, H, I, J, K, L, M, N)
{A, B, C} is the primary key.
{D, E} forms a candidate key.
The following functional dependencies exist among the attributes of the relation:
{A, B} -> {H,I}
{D} -> {F,G}
{J} -> {K,L}
{E} -> {M,N}
我需要把它分解为第二范式,所以我{AB->HI}, {D->FG}, {E->MN}
分成独立的表。但是怎么样{J->KL}
?我应该如何规范这个?
