The H. I. Topi School of Business operates international business programs in 10 locations throughout Europe. The school had its first class of 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 to its alumni, the school holds various events around the world. Events have a title, date, location, and type (eg, reception, dinner, or seminar). The school needs to keep track of which graduates have attended which events. When an alumni attends an event, notes are recorded about information school officials learned from that graduate at that event.
The school also keeps in contact with graduates by mail, email, telephone, and fax interactions. As with events, the school records each time an alum is contacted as well as information learned from the graduate from each of these communications. 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 including the information learned during the past two years from all communications with the graduate, and events the graduate attended.
