Atomicity does not behave completely orthogonally with regard to the other ACID properties of transactions. For example, isolation relies on atomicity to roll back the enclosing transaction in the event of an isolation violation such as a deadlock; consistency also relies on atomicity to roll back the enclosing transaction in the event of a consistency violation by an illegal transaction.
Alternatively, we may say that a logical transaction may be composed of several physical transactions. Unless and until all component physical transactions are executed, the logical transaction will not have occurred. An example of an atomic transaction is a monetary transfer from bank account A to account B.
The WS-Transaction specification describes coordination types that are used with the extensible coordination framework described in the WS-Coordination specification.

In transaction processing, databases, and computer networking, the two-phase commit protocol (2PC, tupac) is a type of atomic commitment protocol (ACP). It is a distributed algorithm that coordinates all the processes that participate in a distributed atomic transaction on whether to commit or abort (roll back) the transaction.
(This is simply a conceptual example, not correct code. For example, it behaves incorrectly if node is deleted from the list during the transaction.) CCRs also permit a guard condition, which enables a transaction to wait until it has work to do: atomic (queueSize > 0) { remove item from queue and use it }
