Question
State which of the schedules are serializable. For each serializable schedule give an equivalent serial schedule. a. S1 = {read(T1,x), read(T2,y), read(T1,z), read(T3,z), read(T2,x), read(T1,y)}
State which of the schedules are serializable. For each serializable schedule give an equivalent serial schedule.
a. S1 = {read(T1,x), read(T2,y), read(T1,z), read(T3,z), read(T2,x), read(T1,y)}
b. S2 = {read(T1,x), write(T2,y), read(T1,z), read(T3,z), write(T2,x), read(T1,y)}
c. S3 = {read(T1,x), write(T2,y), read(T1,z), read(T3,z), write(T1,x), read(T2,y)}
d. S4 = {read(T1,x), read(T2,y), read(T1,z), read(T3,z), write(T1,x), write(T2,y)}
e. S5 = {write(T1,x), read(T2,y), read(T1,z), read(T3,z), read(T1,x), write(T2,y)}
