    Basically for As/Alevel ICT you will have to do tons and tons of course work, however the exams are easy though. Basically you have some work to do over xmas. At least we know someone will be working hard over the holidays. You will have many long nights, rememer that from me.


    What level DFD do you need to go to?

    A data-flow diagram shows just that - how data flows into, out-of and around between entities, as they interact with the system

    You start off with level zero, or the context diagram.

    Then you "zoom in" and focus on the main processes in the system (level 1).

    Then you zoom in further and divide those processes in level 1 and show them as smaller processes for level 2.
