In the course of a database management audit a review of database management system (DBMS) audit log highlights that due to an error some transactions were partially performed and not rolled back. A violation of which transaction processing feature has occurred?
Atomicity
Durability
Consistency
Isolation
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 are invisible to external operations. Durability guarantees that a successful transaction will persist, and cannot be undone.
