Q.1. You are hired to design database for a university considering following requirements and constraints. Please consider following for your database design. . University keeps track of each student's name, student number, social security number, current address and phone, permanent address and phone, birthdate, sex, class, major department, minor department, and degree program. Sometimes university needs to refer to the city, state, and zip of the student's permanent address, and to the student's last name. Both social security number and student number have unique values for each student. A department may or may not have any minor student but must have major students. A student must declare a major department. A student can only declare one major department. Note that some students may not have a minor department and can declare only one minor department. Each department is described by a name, department code, office number, office phone, and college to which it belongs. Both department name and department code have unique values for each department. Each course has a course name, description, course number, credit hours, level, and offering department. The value of course number is unique for each course. Each course must be offered by a department. A department may offer many courses. It is possible that a department does not offer any course. A course may have many sections. Each section has an instructor, semester, year, course, and section number. The section number distinguishes different sections of the same course that are taught during the same semester and year. A section will always be associated with a course. University also manages a grade report that shows student, his/her section, letter grade, and numeric grade. . . Given above conditions, design an ER diagram for this application using Chen notation only (Chen notation is the same as the one you used for assignment #1). ER Diagram drawn using any other notation will not be graded. Write any unspecified assumptions that you need to make the specification complete. Identify attributes and key attributes for each entity type and/or relationship type. You can always list additional attributes as per your needs also include Participate constraints and Cardinality Ratio
