I have gone through link https://stackoverflow.com/questions/40859477/is-a-strict-schedule-always-serializable But i don’t think example given there is correct.I don’t think it is strict schedule as T2 is reading x which is written by T1 , even before T1 commits. Hence is any other example which is strict but not serializable?
