Discuss how you would test for view serializability using a labeled precedence graph. Using the above method, determine whether the following schedules are view serializable:
(i) S 1 = [R 1 (x), W 2 (x), W 1 (x)]
(ii) S 2 = [W 1 (x), R 2 (x), W 3 (x), W 2 (x)]
(iii) S3 = [W1(x), R2(x), R3(x), W3(x), W4(x), W2(x)]
i. Cycle so not view serializable.
ii. Cycle between T1 and T2 so not view serializable.
iii. Can show using above method that this is a view serializable schedule
