The transaction processing is the processing of business transaction by computers connected by computer networks.
Transaction processing systems are the most widely used information systems. The predominant function of transaction processing system is to record data collected at the boundaries of organizations, in other words, at the point where the organization transacts business with other parties.
Transactions processing system have to handle high volume efficiently, avoid errors due to concurrent operations, avoid producing partial results, grow incrementally, avoid downtime, never lose results, offer geographically distribution, be customizable, scale up gracefully, and be easy to manage. Many transaction processing systems also call for very large processing of data by hundreds of users using equipment distributed over dozens of locations spread over a vast geographical area.
Large enterprises in transportation, finance, retail, telecommunications, manufacturing, government, and the military are utterly dependent on transaction processing applications for electronic reservations, banking, stock exchanges, order processing, music and video services, shipment tracking, government services, telephone switching, inventory control and command and control.
Many large hardware and software vendors receive much of their revenue from components of transaction processing system, such as IBM, HO, Oracle, Microsoft, Dell, Red Hat and EMC.
