A transaction processing system or transaction server is a software system, or software/hardware combination, that supports transaction processing. Transaction Processing is not limited to application programs. Transaction processing systems consist of computer hardware and software hosting a transaction-oriented application that performs the routine transactions necessary to conduct business. Transaction processing is a style of computing that divides work into individual, indivisible operations, called transactions. Other transaction monitor functions include deadlock detection and resolution (deadlocks may be inevitable in certain cases of cross-dependence on data), and transaction logging (in journals) for forward recovery in case of massive failures. OLTP (online transaction processing) is a class of software programs capable of supporting transaction-oriented applications. Transaction processing systems also attempt to provide predictable response times to requests, although this is not as critical as for real-time systems. Without proper transaction monitoring, double bookings may occur. If one or more events have failed then the transaction is rolled back, meaning each event is requested to abort all actions. A Transaction Processing System (TPS) is a type of information system that collects, stores, modifies and retrieves the data transactions of an enterprise.

While this type of integrity must be provided also for batch transaction processing, it is particularly important for online processing as of an airline seat reservation system is accessed by multiple operators, after an empty seat inquiry, the seat reservation data must be locked until the reservation is made, otherwise another user may get the impression a seat is still free while it is actually being booked at the time.
History One of the first transaction processing systems was American Airline SABRE system, which became operational in 1960. An effective TPS system serves to maintain the ACIDity properties (i.e., atomicity, consistency, isolation, and durability) of transactions and must be. In case of a failure preventing transaction completion, the partially executed transaction must be rolled back by the TPS. A transaction processing system (TPS) or transaction server is a software system, or software/hardware combination, that supports transaction processing. If an electronic payment is made, the amount must be either both withdrawn from one account and added to the other, or none at all.
A Transaction Processing System or Transaction Processing Monitor is a set of information which process the data transaction in database system that monitors transaction programs.The essence of a transaction program is that it manages data that must be left in a consistent state.
