Pаrt II (10 pоints) – Structurаl аnd Behaviоral Mоdeling Canvas is a course management system. A system administrator uses the Canvas system to create course templates and to enroll students. A professor can use the system to add teaching materials including lecture notes and assignments, and to enter student grades. A student can access his/her enrolled courses to read and download teaching materials, to submit assignments, and to check grades. Canvas ensures that only an authorized person can access the relevant information, i.e. only the professor of a class can enter/change the grades of the students taking that class, and only a student can check his/her own grades. (1) (5 points) Develop a Structural Model (class diagram) based on the above system description (show essential entity classes, a few boundary and controller classes, and their correct relationships); (2) (5 points) Develop a UML Behavioral Model (sequence diagram) for the scenario that a student successfully submits a homework assignment including the authentication step (show instances of all relevant classes – boundary, controller, and entity classes; and all important messages - operations/methods with necessary parameters).
