Computer reservation system
Computer reservation systems, or central reservation systems (CRS), are computerized systems used to store and retrieve information and conduct transactions related to air travel, hotels, car rental, or other activities. Originally designed and operated by airlines, CRSs were later extended for use by travel agencies, and global distribution systems (GDSs) to book and sell tickets for multiple airlines. Most airlines have outsourced their CRSs to GDS companies, which also enable consumer access through Internet gateways.
Modern GDSs typically also allow users to book hotel rooms, rental cars, airline tickets as well as other activities and tours. They also provide access to railway reservations and bus reservations in some markets, although these are not always integrated with the main system. These are also used to relay computerized information for users in the hotel industry, making reservation and ensuring that the hotel is not overbooked.
Airline reservations systems may be integrated into a larger passenger service system, which also includes an airline inventory system and a departure control system. The current centralised reservation systems are vulnerable to network-wide system disruptions.
The MARS-1 train ticket reservation system was designed and planned in the 1950s by the Japanese National Railways' R&D Institute, now the Railway Technical Research Institute, with the system eventually being produced by Hitachi in 1958. It was the world's first seat reservation system for trains. The MARS-1 was capable of reserving seat positions, and was controlled by a transistor computer with a central processing unit and a 400,000-bit magnetic drum memory unit to hold seating files. It used many registers, to indicate whether seats in a train were vacant or reserved to accelerate searches of and updates to seat patterns, for communications with terminals, printing reservation notices, and CRT displays.
In 1953 Trans-Canada Airlines (TCA) started investigating a computer-based system with remote terminals, testing one design on the University of Toronto's Ferranti Mark 1 machine that summer. Though successful, the researchers found that input and output was a major problem. Ferranti Canada became involved in the project and suggested a new system using punched cards and a transistorized computer in place of the unreliable tube-based Mark I. The resulting system, ReserVec, started operation in 1962, and took over all booking operations in January 1963. Terminals were placed in all of TCA's ticketing offices, allowing all queries and bookings to complete in about one second with no remote operators needed.
In 1953 American Airlines CEO C. R. Smith chanced to sit next to R. Blair Smith, a senior IBM sales representative, on a flight from Los Angeles to New York. C.R. invited Blair to visit their Reservisor system and look for ways that IBM could improve the system. Blair alerted Thomas Watson Jr. that American was interested in a major collaboration, and a series of low-level studies started. Their idea of an automated airline reservation system (ARS) resulted in a 1959 venture known as the Semi-Automatic Business Research Environment (SABRE), launched the following year. By the time SABRE was fully completed in December 1964, it was the world's first online transaction processing system, and at the time, "the world's largest private real time commercial data processing system".
Other airlines established their own systems. Pan Am launched its PANAMAC system in 1965 and Delta Air Lines launched DELTAMATIC in 1965, both of which had been developed by IBM alongside SABRE as part of the SABER joint project (and then American insisted on a different name for its project, resulting in the name SABRE). DELTAMATIC was followed by the Delta Automated Travel Account System (DATAS) in 1968.
In 1965, IBM generalized its work on the SABER joint project into Programmed Airline Reservation System (PARS), which became the industry standard by 1971. From 1971 to 1973, American migrated SABRE to a PARS-based system.
