1. Briefly describe a real-world sequence of steps (other than those mentioned in lecture) that should be per- formed within a database transaction. What are the risks in your scenario if all ACID transactional properties are not guaranteed? 2. Determine whether each of the following schedules are conflict serializable. Show how you arrived at your conclusions: (a) n(A); w1(A):r2(B); w2(B);r2(A); w1(B): (b) (A); r2(A); r2(B); w2(B); w1(A); (c) r2(A):(B); 22(A): 73(A); w1(B): w3(A); r2(B); w2(B); (d) w(A); r2(A); w1(B); wy(C);r(C);r.(B); wy(D); W.(E);rs(D); ws(E)
