In timestamp ordering, W-timestamp(Q) denotes the largest timestamp of any transaction that executed write(Q) successfully. Suppose that, instead, we defined it to be the timestamp of the most recent transaction to execute write(Q) successfully.Would this change in wording make any difference? Explain your answer.
