CONFIRM was an ambitious IT project supposed to create a single computer reservations system/global distribution system used by airline, rental car, and hotel companies. It is often used as a case study as an example of a major failure in project management .
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. [6] It was the world's first seat reservation system for trains. [7]
To cleanly separate code for rapidly changing system behavior (what a system does) versus slowly changing domain knowledge (what a system is), instead of combining both in one class interface; To help software developers reason about system-level state and behavior instead of only object state and behavior;
SystemC is a set of C++ classes and macros which provide an event-driven simulation interface (see also discrete event simulation).These facilities enable a designer to simulate concurrent processes, each described using plain C++ syntax.
In addition to airlines, the CRS is also used to book train travel, cruises, car rental, ferry reservations, and hotel rooms. Amadeus also provides New Generation departure control systems to airlines. [1] Amadeus IT Group is a transaction processor for the global travel and tourism industry.

BOOPSI (Basic Object Oriented Programming System for Intuition) was introduced with OS 2.0 and enhanced Intuition with a system of classes in which every class represents a single widget or describes an interface event. This led to an evolution in which third-party developers each realised their own personal systems of classes.
