Draw a DFD for the following case.

Tap on Attendance System:

A university is considering an ID tap on attendance system. The Teacher sets the system at the start

of the session by selecting the session details. Students tap their IDs. Everything is recorded in the

Student Attendance Database. At the end of the day, Student Affairs runs an attendance check on the

Student attendance Database. The system would then automatically email students who missed

classes an email warning and flag those students who have now exceeded their limit$.$ Student Affairs

would contact the students by email to let student know they have been removed from the course

with email copy to the tutor.
