Requirements: A college course may have zero, one or more sections. Attributes of a course include a unique Course_ID, Course_Name, and Credit Units. Attributes of a section include Section_Number (e.g., 001 or 002) and Semester (e.g. Fall) and Year. A combination of Section_Number, Semester and Year can distinguish one section from another section for the same course but does not uniquely identify a section. Each course has one instructor.
