[Yr11 Information Technology] Data Flow Diagrams

[Laurie Savage]

The old IPM text IT at work was very thorough on DFDs and other diagrams. See if you can find a copy.

Subject: [Yr11 Information Technology] Data Flow Diagrams


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. 

How deep are we expected to cover DFDs? The study design lists: tools for representing data flows, including data fl ow diagrams.

Does anyone have any notes to better explain level 1 and level 2?

Regards


Rob
