Which of the following properties are specific to the durability property? In the event of system failure, no transactions that were done can be undone. If any of the transaction parts violates an integrity constraint, the entire transaction must be aborted. A transaction should be treated as a single logical unit of work that is indivisible. Data used in one transaction cannot be used in another transaction until the first transaction is completed.

Transaction Processing

Transaction processing is a computational style generally performed by server computers, which supports interactive applications (apps). Transaction processing is also known as information processing, which divides the work into indivisible and individual operations called transactions. The transaction is a set of tasks; a single task is considered as the minimum processing unit that cannot be divided again.
