Dick Scudder, the chairperson of the information technology department at the University of Denver, needs to create a database to keep track of all the courses offered by the department. In addition, Dick would like the database to include each instructor’s basic contact
information, such as ID number, name, office location, and phone number. Currently, Dick has nine instructors (seven full-time faculty members and two adjuncts) in the department. For each course, Dick would like to keep track of the course ID, title, and number of credit
hours. When courses are offered, the section of the course receives an ID number, and with that number, the department keeps track of which instructor is teaching the course. Finally, Dick needs to be able to keep track of the IT students and to know which courses
each student has taken. The information he would like to know about each student includes ID number, name, and phone number. He also needs to know what grade the student receives in each course.

Dick has asked you to create an ERD from the information described above.
