Four transactions are presently running: (The abbreviation R(A) means Read(A), and so on) • T1: R(A),R(B),R(J),W(A),W(B),R(D),R(E),R(G) • T2: R(C),R(G),W(C),R(H),W(H),R(D) • T3: W(J),R(C),W(C) • T4: R(G),W(D),R(J) The following is a schedule for these transactions. T1:R(A), T4:R(G), T3:W(J), T1:R(B), T1:R(J), T1:W(A), T3:R(C), T3:W(C), T2:R(C), T2:R(G), T1:W(B), T1:R(D), T2:W(C), T1:R(E), T1:R(G), T2:R(H), T2:W(H), T4:W(D), T4:R(J), T2:R(D) 1. List all conflicts in these transactions. 2. Is the schedule conflict serializable? If it is, to which serial schedule(s) is it equivalent?
