To convert into 2NF find $PQ^+$ and $S^+$ So R(P, Q, R, S, T) will decompose into $R_1(P,Q,S), R_2(P,Q,R), R_3(S,T)$ Please mention the source of this question in title and if it is a self doubt mention it in title and ask question in question description. 0 votes 0 votes Please log in or register to add a comment.
