2. Atomicity (database systems) - Wikipedia

   en.wikipedia.org/wiki/Atomicity_(database_systems)

   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.

3. Two-phase commit protocol - Wikipedia

   en.wikipedia.org/wiki/Two-phase_commit_protocol

   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.

4. ACID - Wikipedia

   en.wikipedia.org/wiki/ACID

   Non-trivial transactions typically require a large number of locks, resulting in substantial overhead as well as blocking other transactions. For example, if user A is running a transaction that has to read a row of data that user B wants to modify, user B must wait until user A's transaction completes.

5. WS-Atomic Transaction - Wikipedia

   en.wikipedia.org/wiki/WS-Atomic_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.

6. WS-Transaction - Wikipedia

   en.wikipedia.org/wiki/WS-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 ...

8. X/Open XA - Wikipedia

   en.wikipedia.org/wiki/X/Open_XA

   Since XA uses two-phase commit, the advantages and disadvantages of that protocol generally apply to XA. The main advantage is that XA (using 2PC) allows an atomic transaction across multiple heterogeneous technologies (e.g. a single transaction could encompass multiple databases from different vendors as well as an email server and a message broker), whereas traditional database transactions ...

   The proposal backed by Harris would only apply to a narrow — and very wealthy — slice of the population: people whose net worth is at least $100 million. That's about 10,660 people in the U.S ...
