List rules for diagramming DFDs. Draw a context diagram and expand it to top level logical DFD for Student Enrollment System. The enrollment process works as follows. • Students send in an application form containing their personal details and their desired course. • The university checks that the course is available and that the student has necessary academic qualifications. • If the course is available, the student is enrolled in the course, and the university confirms the enrollment by sending a confirmation letter that they are registered for the course. • If the course is unavailable, the student is sent a rejection letter.
