QUESTIONS: You are required to provide your own case study of a system development. Your case study description should be enough for you to draw the needed diagrams based on the question requirements below. The case study should explain well objects interactions in the system and as well as at least a sample process involved. Based on the above, you are required to: a. Provide a case study that involves the process of registration or payment with the needed descriptions to show objects interactions. The case study should include the description or flow of the registration or payment process/activity. (10 marks) b. Develop a Sequence diagram and Communication diagram to represent the objects interactions based on the case study provided in (a). (20 marks) c. Develop an Activity diagram to represent the process/activity described in the case study provided in (a). (20 marks) You are encouraged to supplement additional information to support your illustration of the requirement and model. State your assumption clearly (if any).
