Problems are based on the class scheduling 3NF relations along with some sample data shown in Figure 6-11. Not shown in this figure are data for an ASSIGNMENT relation, which represents a many-to-many relationship between faculty and sections. Note that values of the SectionNo column do not repeat across semesters.
