Assignment 2: UML Conceptual View and Process View

Due Week 3 

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:

1. 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.
   1. An automated ticket-issuing system used by passengers at a railway station.
   2. A
      computer-controlled, video-conferencing system that allows video,
      audio, and computer data to be visible to several participants at the
      same time.
2. 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.
3. 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. 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 object-oriented 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.

Discssion 1

“UML Class Notations ” Please respond to the following:

• Compare and contrast the UML class diagram relationships that can exist between classes and explain when you would use each type of relationship to model a software project. 
• Explain how you could utilize open-source software to assist in the development of software and provide at least two unique examples of open-source code that you could potentially use for development purposes.

Disscssion 2

“Unit Testing” Please respond to the following:

• Describe one strategy for choosing unit testing cases. Provide an example of how the strategy is applied in a specific development context.
• Explain the differences between unit testing and component testing, and how these differences affect your strategy for choosing component testing cases.
