Assignment (3) - TEAM ASSIGNMENT
CS3430 Due Friday Sept. 23

The description for a database is given. You are to discuss the E-R diagram for this database as a group. Submit a cover sheet with your solution to indicate the day(s), date and time that you met to discuss the problem and the team members who were presented at the discussion meeting(s).
3.16 Consider the following set of requirements for a university database that is used to keep track of students' transcripts. This is similar but not identical to the database shown in Figure 1.2:

a. The university keeps track of each student's name, student number, social security number, current address and phone, permanent address and phone, birthdate, sex, class (freshman, sophomore, ..., graduate), major department, minor department (if any), and degree program (B.A., B.S., ..., Ph.D.). Some user applications need 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.

b. Each department is described by a name, department code, office number, office phone, and college. Both name and code have unique values for each dapartment.

c. Each course has a course name, description, course number, number of semester hours, level, and offering department. The value of course number is unique for each course.

d. 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/year; its values are 1, 2, 3, ...; up to the number of sections taught during each semester.

e. A grade report has a student, section, letter grade, and numeric grade(0, 1, 2, 3, 4 for F, D, C, B, A, respectively). Design an ER schema for this application, and draw an ER diagram for that schema. Specify key attributes of each entity type and structural constraints on each relationship type. Note any unspecified requirements, and make appropriate assumptions to make the specification complete.

If possible, do your best to type your answers. This way, you will have it for later use and grading would be easier too.
