Data Flow Diagrams</DIV>
<DIV><BR></DIV>I'm preparing for DFDs, something I've not taught before. The
Potts text give two pages of, too me, brief cover. When I look at the DFD
examples on the VITTA support cd, I feel I'm way short of knowing much about
them. Context/level 0 diagrams are fine, but going further seems to leave a
lot of interpretation to the imagination. Given that my students aren't very
worldly, I don't expect them to grasp the topic very easily.
<DIV><BR></DIV>
<DIV>How deep are we expected to cover DFDs? The study design
lists: <SPAN class=Apple-style-span
style="FONT-SIZE: 11px; FONT-FAMILY: Times">tools for representing data flows,
including data fl ow diagrams.</SPAN></DIV>
<DIV><BR></DIV>
<DIV>Does anyone have any notes to better explain level 1 and level 2?</DIV>
<DIV><BR></DIV>
<DIV>Regards<BR>
