The UML is used to describe the conceptual view and process view of an automated ticket-issuing system to be used by passengers on a railway station and for a computer-controlled video-conferencing system used with video, audio, and computer data to participants. Diagrams will show the conceptual and process view of these two systems and have justification for each of the decisions in the design. There is an explanation on how the final solution of the four diagrams were created to allow people to perform the tasks they need.
An automated ticket-issue system is used by passengers to order tickets for the railway station.
