Which property of a transactional workload guarantees that each transaction is treated as a single unit that either succeeds completely or fails completely?

  1. atomicity
  2. isolation
  3. durability
  4. consistency

Answer(s): A

Explanation:

The purpose of making transactions atomic is to prevent different transactions from interfering with one another. This can only happen if more than one user process is trying to access the database at the same time, as when a server allows several clients to use it concurrently. The simplest way to enforce atomicity is for the DBMS to refuse to start any transaction until the previous one has committed.
