A level 0 data flow diagram (DFD), also known as a context diagram, shows a data system as a whole and emphasizes the way it interacts with external entities. This DFD level 0 example shows how such a system might function within a typical retail business. Data flow diagramming is a hi...
Level 0 data flow diagrams show a single process node and its connections to external entities. For instance, the example shown below illustrates the hotel reservation process with the flow of information between admin and guests. Data Flow Diagram Level 0 Template (Click on image to modify ...
