1. Consider the database schema: STUDENT (Name, Student_number, Class, Major), COURSE (Course_name, Course_number, Credit_hours, Department), SECTION (Section_identifier, Course_number, Semester, Year, Instructor), PREREQUISITE (Course_number, Prerequisite_number), where example values of Department are: CS, MATH, MUSIC, and example values for Course_number are: CS3130, MATH1003, MUSIC2343 (i.e. each Course_number has the Department as prefix). a. If the name of the 'CS' (Computer Science) Department changes to CSSE (Computer Science and Software Engineering) Department and the corresponding prefix for the course number also changes, identify the columns in the database that would need to be changed. b. Can you restructure the columns in COURSE, SECTION, and PREREQUISITE tables so that only one column will need to be changed? Note that in the COURSE table, the column Course Dept will not be needed after the above change, since it is redundant with the Department column
