Scenario: Your team has been assigned the responsibility to design an online university registration system. The system should enable the staff of each academic department to examine the courses offered by their departments, add and remove courses, and change the information about them (e.g., the maximum number of students permitted). It should permit students to examine currently available courses, add and drop courses to and from their schedules, and examine the courses for which they are enrolled. Department staff should be able to print a variety of reports about the courses and the students enrolled in them. The system should ensure that no student takes too many courses and that students who have any unpaid fees are not permitted to register (assume that fees data are maintained by the university's financial office, which the registration system accesses but does not change). Q1. Based on the scenario provided above, draw a use case diagram. Identify all major use cases based on the functionality of the system and include them in your diagram. Mandatory include short descriptions of the actor(s) and the major use cases. Q2. Based on the scenario provided above, create a domain model (structural model) by including domain classes (using the 7 steps for structural modeling discussed) to support the online registration system of the university. Include all major (important) classes to show what they need information about. You can begin by doing an analysis of the use-case to identify the objects for your classes. Brainstorm with your team members to decide on the final set of domain classes in your diagram. Make sure to include at least 8 major classes. Include attributes and relationships, making assumptions about how the classes are related. Show multiplicities for all associations. All classes should show some attributes, and some of your classes should include the relevant operations. Mandatory include short description for each domain class in your diagram. You may copy your diagram into a Word document and provide the descriptions. You can use Lucidchart or Visio for drawing the models. Q3. Based on the domain model created in Q2, draw an object diagram by instantiating your domain model with a set of appropriate attribute values. Review your object model for any discrepancy in the domain model and provide an explanation, if any
