10IPT: Solution Design & Visualisation

Today we'll be revisiting some old tools for visualising systems, because they are an important part of the design stage in the SDLC. Those tools are: context diagrams, data dictionaries, data flow diagrams and system flowcharts.
  1. On the first side of the worksheet (figures 11.2 and 11.3), use the context diagram and data dictionary together to fill in the other's gaps. (In the context diagram, you need to label the unlabelled dataflows.)
  2. Use the information from the A5 handout to fill out the data flow diagram and the system flowchart, which focuses on process 4 of the DFD.
