An IS auditor analyzing the audit log of a database management system (DBMS) finds that some
transactions were partially executed as a result of an error, and are not rolled back. Which of the
following transaction processing features has been violated?

A.
Consistency

B.
Isolation

C.
Durability

D.
Atomicity

Explanation:

Atomicity guarantees that either the entire transaction is processed or none of it is. Consistency
ensures that the database is in a legal state when the transaction begins and ends, isolation
means that, while in an intermediate state, the transaction data is invisible to external operations.
Durability guarantees that a successful transaction will persist, and cannot be undone.
