2. Atomicity (database systems) - Wikipedia

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

   An example of an atomic transaction is a monetary transfer from bank account A to account B. It consists of two operations, withdrawing the money from account A and saving it to account B. Performing these operations in an atomic transaction ensures that the database remains in a consistent state , that is, money is neither lost nor created if ...

3. Long-running transaction - Wikipedia

   en.wikipedia.org/wiki/Long-running_transaction

   Long-running transactions (also known as the saga interaction pattern [1] [2]) are computer database transactions that avoid locks on non-local resources, use compensation to handle failures, potentially aggregate smaller ACID transactions (also referred to as atomic transactions), and typically use a coordinator to complete or abort the transaction.

4. ACID - Wikipedia

   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.

5. 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 ...

6. Database transaction schedule - Wikipedia

   en.wikipedia.org/wiki/Database_transaction_schedule

   Examples of such operations are requesting a read operation, reading, writing, aborting, committing, requesting a lock, locking, etc. Often, only a subset of the transaction operation types are included in a schedule. Schedules are fundamental concepts in database concurrency control theory. In practice, most general purpose database systems ...

7. 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.

9. Transaction processing - Wikipedia

   en.wikipedia.org/wiki/Transaction_processing

   Transaction-processing systems ensure database integrity by recording intermediate states of the database as it is modified, then using these records to restore the database to a known state if a transaction cannot be committed. For example, copies of information on the database prior to its modification by a transaction are set aside by the ...
