Data Flow Diagram
A data flow diagram (DFD) is a two-dimensional graphical representation of the flow of data through an information system. DFD helps us in identifying existing business processes. DFD enables you to represent the processes in your information system from the viewpoint of data and visualize how the system operates, what the system accomplishes and how it will be implemented, when it is refined with further specification.
Data flow diagrams are used by systems analysts to design information-processing systems but also as a way to model whole organizations. There are two types of DFDs, logical data flow diagrams and physical data flow diagrams, both of which support a top-down approach to systems analysis. DFDs can also be grouped together to represent a sub-system of the system being analyzed.
Data Flow Diagram Software
Data Flow Diagram software is also called DFD software. With Edraw's pre-defined templates and ready-made shapes, the designers can rapidly create structured analysis diagram, information flow diagram, process-oriented diagram, data-oriented diagram and data process diagrams as well as data flowcharts, business process diagrams, work flow diagrams, value stream maps, TQM diagrams, and cause and effect diagrams. To format the style, you can use Edraw's nice-looking pre-defined themes with one click, or you can customize through color, size and line setting. It has rich color schemes and fill options, as well as abundant line styles. Once you're done, you can print it or export to PDF and other graphics formats.
