Consider the following set of requirements for a UNIVERSITY database that is used to keep track of students' transcripts. The university keeps track of each student's social security number, student number, major department, and minor department (if any). Both social security number and student number have unique values for each student. Each department is described by a name and department code. Both name and code have unique values for each department. Each course has a course number, and offering department. The value of course number is unique for each course. Each section has a 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. 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.

Question

Consider the following set of requirements for a UNIVERSITY database that is used to keep track of students' transcripts.

The university keeps track of each student's social security number, student number, major department, and minor department (if any). Both social security number and student number have unique values for each student.
Each department is described by a name and department code. Both name and code have unique values for each department.
Each course has a course number, and offering department. The value of course number is unique for each course.
Each section has a 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.
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.
