A data flow model example is a diagrammatic representation of the flow and exchange of information within a system. Data flow models are used to graphically represent the flow of data in an information system by describing the processes involved in transferring data from input to file storage and report generation. A data flow model diagram can be created by going through the following steps: select a data flow model template from EdrawMax, name the data flow model diagram, add an external entity that starts the process, add a process to the data flow diagram, add a data store to the diagram, continue to add items to the DFD, and add data flow to the data flow diagram.
