Q2-Create a set of use cases for an online university registra- tion system. The system should enable the staff of each academic department to examine the courses
offered by their department, add and remove courses, and change the information about them (e.g., the maximum num- ber 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 a fees data store is maintained by the university’s financial office, which the
registration system accesses but does not change.)

Q3-Create a set of use cases for the following system: A Real Estate, Inc. (AREI), sells houses. People who want to sell their houses sign a contract with AREI and
provide information on their house. This information is kept in a database by AREI, and a subset of this information is sent to the citywide multiple listing service
used by all real estate agents. AREI works with two types of potential buy- ers. Some buyers have an interest in one specific house. In this case, AREI prints
information from its database, which the real estate agent uses to help show the house to the buyer (a process beyond the scope of the system to be modeled). Other
buyers seek AREI’s advice in find- ing a house that meets their needs. In this case, the buyer completes a buyer information form that is entered into a buyer
database, and AREI real estate agents use its infor- mation to search AREI’s database and the multiple listing service for houses that meet their needs. The results of
these searches are printed and used to help the real estate agent show houses to the buyer.
