This is a subjective question, hence you have to write your answer in the Text-Field given below. Figur 308 s (a) and (b) show two independent sequences of reads and writes for data items in a distributed DB across various nodes P1, P2, P3, P4 on a timeline "R. X-V" at Pi means read operation on data item X returns value V at node Pi and "W: Y-V" at Pj means data item Y is written with value V by node Pj. In each case, evaluate if the sequence satisfies or violates causal consistency? Give reasons for your answer.
