With regards to transaction processing, any DBMS should be capable of:

  • A.Ensuring that transactions are free from interference from other users.
  • B.Parts of a transaction are not lost due to a failure.
  • C.Transactions do not make the database inconsistent.
  • D.All of the above.

Answer: D

Correct answer: All of the above.

All three are the ACID guarantees in other words: freedom from interference is isolation, not losing part of a transaction on failure is atomicity and durability, and not leaving the database inconsistent is consistency. A DBMS worth the name provides all of them.
