TM354/THE-Final/Other Branches 3 of 6 2020-2021/Spring Question 3:20 Marks) 3.1 20 Marks A part of a software development scenario related to graduate student recruitment system in a university is given below. 3.1.1 identify the classes and their corresponding attributes in the given scenario 5 Marks 3.1.2 Build an initial level class diagram to store the entities details into a database based on 15 Marks the given below assumptions. You are required to The system is expected to keep information about the graduate students from all faculties, details of the companies registered, available job vacancies, available trainings etc. The university will keep students details in the system every semester after their graduation. The student details to be stores in the system are student ID, name, DOB, major, year graduated, GPA, contact number, email address and the major. There is a dedicated department to manage the process. The department details are department ID, description, email address, and telephone number. The department staff are responsible for all the activities related the process. For each staff, the database should record the staff id, name, address, telephone and email address. The two types of the staff are front-office staff and back-office staff. The front office staff is the contact person with the recruitment companies.
