=== [[Atomic commit]] ===
An atomic commit is an operation where a set of distinct changes is applied as a single operation. If the atomic commit succeeds, it means that all the changes have been applied. If there is a failure before the atomic commit can be completed, the "commit" is aborted and no changes will be applied.
Algorithms for solving the atomic commig protocol include the [[two-phase commit protocol]] and the [[three-phase commit protocol]].
