The H.I. Topi School of Business operates international business programs in 10 locations throughout Europe. The school had its first class of 9,000 graduates in 1965. The school keeps track of each graduate's student number, name when a student, country of birth, current country of citizenship, current name, current address, and the name of each major the student completed (each student has up to two majors). To maintain strong ties with its alumni, the school holds various events around the world. Events have a title, date, location, and type (e.g., reception, dinner, or seminar). The school needs to keep track of which graduates have attended which events. For an attendance by a graduate at an event, a comment is recorded about information school officials learned from that graduate at that event. The school also keeps in contact with graduates by mail, e-mail, telephone, and fax interactions. As with events, the school records information learned from the graduate from each of these contacts. When a school official knows that he or she will be meeting or talking to a graduate, a report is produced showing the latest information about that graduate and the information learned during the past two years from that graduate from all contacts and events the graduate attended. State any additional assumptions you believe you have to make in order to develop a complete diagram. (Hint: you need a lot of entities for this problem.) Also: Also: a) How could we keep address history (i.e., what changes would you make to the ERD)? b) How could we keep name history?
