Conflict equivalence- Two schedules are conflict equivalent if the order of any two conflicting operations is same in both the two schedules.
View equivalence- Two schedules are view equivalent if -
1) Both the schedules have same set of transactions.
2) If in a schedule a read operation r1[X] of transaction T1 reads the value of X written by a write operation w2[x] of transaction T2 or reads the original value of x,then this must also be the case in the other schedule.
3)If operation w3[Y] of a transaction is the last operation to write the value of Y in schedule S then it must also be the last transaction in the other schedule to do so.
All conflict serializable schedules are view serializable.
But all view serializable schedules are not conflict serializable.
