no it is not view serializable..
reason is there may b 2 schedule possible :
1. T1--->T2
2. T2----->T1z
in case 1 final write of x is done by T2, but in given question final write of x is done by T1. so it violates condition of view serializability.
in case 2 initial read of T1 is updated value by T2 but in original question it is directly reads database.. again condition of view serialization failed..
so not serializable schedule..
