You have been asked to develop UML diagrams to graphically depict and describe the architecture of two (2) unrelated software systems. The first system is for an automated ticket-issuing system used by passengers at a railway station. The second system is for a computer-controlled video conferencing system, located in a corporate office and accessible to senior management that allows video, audio, and computer data to be visible to several participants at the same time. Write a three to five (3-5) page paper in which you: Create two (2) UML diagrams, one (1) showing a conceptual view and one (1) showing a process view of the architectures for each of the two (2) following systems (for a total of four [4] diagrams) through the use of Microsoft Visio or its open source alternative, Dia. Note: The graphically depicted solution is not included in the required page length. An automated ticket-issuing system used by passengers at a railway station. A computer-controlled, video-conferencing system that allows video, audio, and computer data to be visible to several participants at the same time. Describe how you created the conceptual and process view for all four (4) diagrams. In the description, be sure to provide a justification for each key decision in the design. Explain how you arrived at your final solution for the four (4) conceptual and process view diagrams that you have created. Your assignment must follow these formatting requirements: Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions. Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date.

UML Diagrams for Automotive Ticketing and Video Conferencing Systems

The development of Unified Modeling Language (UML) diagrams provides a crucial method for visualizing and understanding software system architectures. In this paper, we explore the conceptual and process views of two distinct systems: an automated ticket-issuing system at a railway station and a computer-controlled video conferencing system used by senior management in a corporate setting. Through detailed creation and analysis of four UML diagrams—two for each system—we demonstrate how to effectively capture the core components and operational processes. The diagrams were created using Microsoft Visio, with the conceptual views illustrating static structures, and the process views depicting dynamic flows of activities. Each design decision is justified in the context of system requirements, usability, and scalability.

System 1: Automated Ticket-Issuing System at Railway Stations

Conceptual View

The conceptual UML diagram for the railway ticket system emphasizes static class structures and the key entities involved. Central classes include Passenger, TicketMachine, Ticket, and PaymentGateway. The Passenger interacts with the TicketMachine to select destinations, generate tickets, and make payments. The TicketMachine manages ticket creation, while PaymentGateway handles transaction processing. Relationships among classes are modeled to reflect real-world associations, such as the Passenger’s dependency on the TicketMachine for ticket issuance.

Process View

The process UML diagram captures dynamic interactions during ticket purchase. The process begins with the Passenger approaching the TicketMachine and selecting travel details. The TicketMachine validates inputs, processes payment via PaymentGateway, and finally prints the ticket. Decision points include payment success or failure, influencing subsequent steps. The diagram illustrates sequence flows, method calls, and state changes, providing a clear picture of system operations from user interaction to ticket issuance.

System 2: Computer-Controlled Video Conferencing System

Conceptual View

The static diagram for the video conferencing system depicts key classes such as Participant, Conference, MediaStream, and Controller. Participants can join or leave a session, with the Conference class managing the participants list. MediaStream objects handle video, audio, and data streams, while Controller oversees session configurations and permissions. Relationships clarify how participants are connected through media streams managed by the system’s central controller.

Process View

The dynamic diagram outlines the sequence of actions during a conferencing session. It starts with participants logging in, establishing media streams, and sharing data. The Controller manages synchronization and permissions throughout the session. The flow includes participant joins, media stream negotiations, data sharing, and session termination. This view highlights interactions that enable seamless communication and data sharing among multiple users in real time.

Discussion of Design Decisions

The choice to differentiate between conceptual and process views stems from the need to clearly distinguish static system structure from dynamic operational behavior. For the ticketing system, emphasizing class relationships supports understanding of data organization, whereas process diagrams clarify the user interaction flow. For the conferencing system, structural diagrams depict media management, while process diagrams reflect real-time interactions. Justification for these decisions lies in aligning UML views with system requirements, ensuring clarity for stakeholders and facilitating development.

Conclusion

Creating these UML diagrams involved iterative refinement to capture essential system features while maintaining simplicity. Decision points, such as including payment validation or media stream negotiation, were driven by critical system functions. Using Visio enabled precise modeling of relationships and interactions, aiding in the comprehensive understanding of each system’s architecture. This process fosters better communication among developers, analysts, and stakeholders, ultimately supporting effective system implementation.
