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.
