Based on Figure 1.2 and Figure 2.1 (provided), I've determined that the section_identifier in the SECTION schema serves as the unique identifier for that schema. Now, suppose that I adjust the section_identifier so that it only stores the section number for each course (for instance, MTH311-02 and MTH150-02 would have the same section number, 02). What changes (if any) would be required in other schemas due to this adjustment?
