The application provides the following functionality:
Student registration— This functionality enables new students to create and maintain their account information. The account information includes the student's first name, last name, address, e-mail, login name, and password.
Student authentication— This module handles the student login process, such as verifying the login name and password. This ensures that only registered students browse the course catalog and purchase courses for enrollment.
Course catalog browsing— The Web site displays the current course offerings in the university and their details. The course details include the course title and fee.
Enrollment cart— The enrollment cart module enables students to place their course selection in a shopping cart while browsing the course catalog, and later to view the cart contents before placing an order.
Order processing— The order module enables students to place their orders, and performs the necessary verification before approving them.
Administrator interface— This functionality allows the administrator to view and approve orders for enrollment.
Notification— This functionality causes the system to send e-mail to students when they have enrolled for a course.
