CHECK equvivalance bw given concurrent schedule nd serial schedule T1 T4 T3 T2
given schedule serial schedule (T1 T4 T3 T2)
1) initial read T4 T3 T2 on x T4 T3 T2 on x
2) updated read on y T1:W(y) --> T4:R(y) on y T1:W(y) --> T4:R(y)
3) Final write on y T2 , on z T2 on y T2 , on z T2
hece it is view equivalent to serial schedule T1 T4 T3 T2 nd conflict serializable also
or
conflict serializable -------> view serializable
