A student management system is defined below: With the help of the registrar, a new student establishes his/her account. A student can register classes of his/her choosing during the registration period. If the system found there are pre-requisite violations the student will be de- registered from the violating classes. A student who was de-registered up to three times will be warned. A student whose GPA is between 2.0 to 2.3 is also warned. Students who are warned must see the student adviser to remove the warning. A student whose GPA is less than 2.0 or who was warned three times or who has one outstanding warning without seeing the adviser for one semester will be suspended. A student can apply for graduation or transfer to other schools. If the student passed the graduation check by the registrar, s/he will be put on the list of graduating student Graduating students whose GPA is higher than 3.5 are put in Dean's list, those higher that 3.9 are put in President's list. Anyone who failed the graduation check will receive a warning for reckless application. The school will allow the student to transfer out if s/he didn't owe any money. 1) (5pts) Draw the Use-case diagram of the system; 2) (8 pts) Draw the sequence or collaboration class diagram (don't do both, only one will be graded) for the system.
