Two transactions that run concurrently and generate results that are consistent with the results that would have occurred if they had run separately are referred to as serializable transactions.

  • A.True
  • B.False

Answer: A

Correct answer: True

Serializable transactions produce a result identical to some serial execution of the same transactions, one after another. It is the standard against which concurrency control is judged: the transactions may interleave in any way at all, so long as the outcome could have been produced by running them in some order.
