The Problem Statement
Build a university-wide student registration and management system. The system must enable the university to manage its operations at the student, department, and college levels. This will allow the university to devise more effective ways of: measuring unit performance, control costs, forecast enrollments, and implementing marketing plans.

Course Catalog
Manage the department course catalog which represent all the courses the department has to offer or the courses the department is capable of teaching (Capability)
Course catalogs are updated once a year (if at all); so course catalogs are independent of time but we keep track of last time the catalog was updated
Example of cc responsibilities:
Find course given the course name
Find course given course number
List all courses

What is a course offering
Course Offering
It is the actual class being taught at some point in time. It answers questions such as:
What is the course being offering?
Who is teaching the course
When is it offered?
Where is it offered
Who are the students signed up for the class?

Seat Assignment
The Course Load class is responsible for the student courses in any given semester. It is the set or collection of courses the student took in a semester. It answers the question “What courses did the student complete in a given semester. Without the Course Load it will very difficult to answer such a reasonable question.

The Transcript class is a historical record of all the courses the student took during their stay at the university. The transcript class knows who the student is. It knows the student course load for any given semester.
To find the GPA. retrieve all the course load objects. For each course load object, get all the seat assignments. Iterate over all the seat assignments. For a given seat assignment get the course grade. Total them up grades. Take the average.
Student GPA goes here. It is a calculated attribute (operation).

The question is usually something like what is Jim’s GPA?
Therefore we need to define an operation of the student class that returns the student GPA. We need to define getGPA() operation on the student class.
The student class has a reference to the transcript instance. The getGPA() operation on the student class calls the operation
transcript.CalculateGPA() which calculates the student GPA when requested. The logic is as follows:
Student
CalculateGPA() operation goes here.
Transcript
getGPA() goes here
The CalculateGPA() operation retrieves all the course load objects. For each course load object, get all the seat assignments. Iterate over all the seat assignments. For a given seat assignment get the course grade. Total them up grades. Take the average.
A reference to the transcript instance is part of the student class

For a more modular design financial matters are separated from the student class. The result is the addition of a Student Account class.
We extracted the following classes from the original model.
The focus is on classes to do with revenues.
