Multiple users must be protected from attempting to change the same piece of data at the same time, for example two operators cannot sell the same seat on an airplane.

The system must be able to handle hardware or software problems without corrupting data. Many organizations rely heavily on their TPS a breakdown will disrupt operations or even stop the business. The system must be available during the time period when the users are entering transactions. Transaction processing systems are usually measured by the number of transactions they can process in a given period of time. Performance įast performance with a rapid response time is critical. Each transaction is usually short duration and the processing activity for each transaction is programmed in advance. Rather than allowing the user to run arbitrary programs as time-sharing, transaction processing allows only predefined, structured transactions.

Transaction processing systems also attempt to provide predictable response times to requests, although this is not as critical as for real-time systems. Batch processing Ī Transaction Processing System (TPS) is a type of information system that collects, stores, modifies and retrieves the data transactions of an enterprise. Transaction processing is distinct from and can be contrasted with other computer processing models, such as batch processing, time-sharing, and real-time processing. Encina was discontinued as a product and folded into IBM's TXSeries. NonStop is an integrated hardware and software system specifically designed for transaction processing.

Hewlett-Packard NonStop system – 1976.

This system was used mainly by financial institutions in the 1980s and 1990s.

Transaction Management eXecutive (TMX) was NCR Corporation's proprietary transaction processing system running on NCR Tower 5000-series systems.

Honeywell Multics Transaction Processing.

Digital Equipment Corporation (DEC) Message Control System (MCS-10) for PDP-10 TOPS-10 systems.

"Provides an environment for creating and controlling online transaction processing (OLTP) applications on the VMS operating system." Runs on VAX/ VMS systems.

Digital Equipment Corporation (DEC) Application Control and Management System (ACMS) – 1985.

As of 2012 UNISYS ClearPath Enterprise Servers include Transaction Server, "an extremely flexible, high-performance message and application control system." Burroughs Corporation supported transaction processing capabilities in its MCP operating systems using GEMCOS (Generalized Message Control System of 1976).

A transaction processing monitor for UNIVAC 1100/2200 series computers. UNIVAC Transaction Interface Package (TIP) – 1970s.Transactions for Unix, Extended for Distributed Operations developed by AT&T Corporation, now owned by Oracle Corporation. Non-mainframe versions are called TXSeries. Runs on OS/360 and successors and DOS/360 and successors, IBM AIX, VM, and OS/2. A transaction manager designed for rapid, high-volume online processing, CICS originally used standard system datasets, but now has a connection to the IBM Db2 relational database system. IBM Customer Information Control System (CICS) – 1969.

A joint hierarchical database and information management system with extensive transaction processing capabilities.

IBM Information Management System (IMS) – 1966.

Originally Airline Control Program (ACP). At Amity Unlike most other transaction processing systems TPF is a dedicated operating system for transaction processing on IBM System z mainframes.

IBM Transaction Processing Facility (TPF) – 1960.

The systems were designed for transaction processing and provided an extreme level of availability and data integrity. The Hewlett-Packard NonStop system (formerly Tandem NonStop) was a hardware and software system designed for Online Transaction Processing (OLTP) introduced in 1976.

In addition to airlines TPF is used by large banks, credit card companies, and hotel chains. SABRE was migrated to IBM System/360 computers in 1972, and became an IBM product first as Airline control Program (ACP) and later as Transaction Processing Facility (TPF). Designed to process up to 83,000 transactions a day, the system ran on two IBM 7090 computers. The first transaction processing system was SABRE, made by IBM for American Airlines, which became operational in 1964. 2 List of transaction processing systems.
