Where can i find resources to draw a DFD for an Online Exam Database system?

The DFD is to be for an online system to be used in an institute where students can register themselves, view the courses and the subjects offerd and then register for an online test.

The questions database will store questions with their last access dates so that the questions dont't get repeated.
