Consider three data items D1, D2, and D3, and the following execution schedule of transactions T1, T2 and T3. In the diagram, R(D) and W(D) denote the actions reading and writing the data item D respectively.
  • a)
    The schedule is seriaiizabie as T2; T3; T1;
  • b)
    The schedule is serializable as T2; T1; T3;
  • c)
    The schedule is serializable as T3; T2; T1;
  • d)
    The schedule is not serializable
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Consider three data items D1, D2, and D3, and the following execution ...
We have sequence W2(D2)→ W1(D1). Which means T2 →T1 whereas we also have W1(D1) →R2(D1) which means T1→ T2. Both are not possible. Therefore, schedule is not serializable.
