Data Flow Diagram - Please Help RRS feed

  • Question

  • Hello there. I am not sure that this is the right forum, but it is the closest I found. So I need help with my homework here a bit. I need to design DataFlowDiagram for my database and ER Model. I had a assignment to create a database that manages users who are using computers and then I need to record on what time it was. So I created my database, then I created ER Model.


    ER Model (Chen)



    My databases looks like this:
















    -time (this is where I record time the user was using this PC for instance 02.03.09 2000-2300)



    My teacher told me that everything is correct, but now I need to create DataFlowDiagram. I searched internet today and I can't find the answer. From what I've searched in my mind it looks like this.
