Using the same initial values, what are the final values of a and b if the order of execution is T,S? c. Does this result have any implications for serializability? Write a concurrent schedule for transactions S and T in Exercise 9.4 that illustrates the lost update problem. 9.5 9.6 Apply the standard two-phase locking protocol to the schedule you devised in Exercise 9.5. Will the protocol allow the execution of that schedule?
