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.
The WS-Transaction specification describes coordination types that are used with the extensible coordination framework described in the WS-Coordination specification. It defines two coordination types: Atomic Transaction (AT) for individual operations, and Business Activity (BA) for long running transactions. Developers can use either or both ...
In the context of databases, a sequence of database operations that satisfies the ACID properties (which can be perceived as a single logical operation on the data) is called a transaction. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a ...
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.
Web Service Atomic Transaction is an OASIS standard. To achieve all-or-nothing property for a group of services, it defines three protocols (completion, volatile two-phase commit , and durable two-phase commit), and a set of services.
(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 }
