A local community college has requested help building a class registration database as it moves class registration towards an online system. The system must keep track of students, courses, professors, departments, and which students are enrolled in which courses. The specific database requirements are as follows: All students can enroll in several courses and each course must have several students enrolled. One professor teaches each course but a professor can teach more than one course. Each professor belongs to a department. Additional information to be kept in the database: For each student: First name, last name, e-mail address, phone number, address For each course: Course number, section, name, and description For each professor: First name, last name, title (assistant, associate, adjunct, instructor, ets) For each department: Department name
