What is a Way to know the view Serializability ?

@hem chandra If schedule is conflict serializable then surely view serializable.

If not conflict serializable then you've to check who reads first who writes last and if there is any blind write or not.

And then make polygraph according to order of who reads first and who wrote last. If no cycle in polygraph as well then it will be view serializable.
