Visualizing the data processing and representing the data flow within some information system is better in a way of a diagram. The best type of diagram for that would be the Data Flow one (DFD) which can be created in ConceptDraw PRO using our pre-made stencils, samples and templates for making this process fast and to make the diagram look professional and smart. While drawing such flowchart, you can always mention on it the data storage and data flows, external entities, control transforms, control signals and functional transforms. There are three stencil libraries now available for your use: Data Flow Diagrams one, Yourdon and Coad Notation Library and Gane-Sarson Notation Library. There are many vector symbols and necessary elements in the libraries as well as examples in our product called ConceptDraw STORE as well as in Solutions sector here on this site where you can find various tutorials for simplifying your work with this sophisticated software.
