The “all-or-none” property is commonly referred to as _________

  • A.Isolation
  • B.Durability
  • C.Atomicity
  • D.None of the mentioned

Answer: C

Correct answer: Atomicity

Atomicity is the all-or-nothing property: a transaction either completes in full or has no effect at all. If it fails part way through, everything it has done is rolled back - which is what stops money being debited from one account and never credited to the other.
