Example 2 n RS is a Registration System where professors indicate which courses they will teach on-line. Allow students to select on-line four courses for upcoming semester. No course may have more than 10 students or less than 3 students. When the registration is completed, the system sends information to the billing system. Professors can obtain course rosters on-line. The registrar will maintain the professor info, student info, course info and he is responsible also for creating a course catalog. 2/11/2022 Chapter 7 Copyright © 2014 Pearson Education, Inc.
