Question:
Consider a GRADE_BOOK database where instructors record the points earned by students in courses in an academic department. The data requirements are considered as follows.
Student: consists of number, name, surname, e-mail components. Each faculty member teaches a certain number of courses in each term. Each lesson; The course number is indicated by the sub-branch number and the period in which the course is given. The instructor should set a minimum score for the letter grades A, B, C, D, E, F to be taken for each course he teaches. Students are registered for the course by the instructor. Each lesson has several grading components. (year-long exiam, final, project, etc.) Each component has a maximum score (100 or 50) and a weight value (20% or 10%). The weighted sum of all grading components of a course must be 100. Finally, the grade of the instructor student from each grade component in each course is recorded. (For example, the student can take 1234 from the second sub-section of the CSC2310 course, 84 from the mid-year exaim in the fall semester of 2009. The maximum score of the annual exaim can be determined as 100 and the weight for the course can be determined as 20%.)
Design the EER diagram for the GRADE_BOOK database given above.
