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 ticketissuing system used by passengers at a railway station. The second system is for a computercontrolled 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 (35) 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  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 ticketissuing system used by passengers at a railway station. A computercontrolled, videoconferencing 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 oneinch margins on all sides; citations and references must follow APA or schoolspecific 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. The cover page and the reference page are not included in the required assignment page length. Include charts or diagrams created in Visio or an equivalent such as Dia. The completed diagrams / charts must be imported into the Word document before the paper is submitted. The specific course learning outcomes associated with this assignment are: Compare and contrast among architectural patterns. Develop system models based on the Unified Modeling Language (UML) to address and solve a business problem. Describe the methods of objectoriented design using UML. Use technology and information resources to research issues in software engineering. Write clearly and concisely about software engineering using proper writing mechanics and technical style conventions.
