Consider the following two classes

Student

Student Number

Student Name

Cumulative GPA

Course Taken and Grades

Course

Course Number

Course Name

Number of Credits

Let's define a method for computing Cumulative GPA for students. GPA is calculated by summing the product of the grades for each course and the courses' credits, then dividing that product by the total number of course credits. Based on this,

1. identify the method(s) you will have in either or both classes to compute the cumulative GPA of a student. You may note/enter the methods in the class diagrams above.
2. briefly, using a single sentence, state the function of each method you have defined.
3. If the two classes above evolve into separate tables, note any possible additional tables, fields as attributes, suggest primary and foreign keys for those attributes, and describe relationship cardinality. Show your work in the diagrams above.
