Data Flow Diagram , workflow diagram, process flow diagram

The standards for the Structured Systems Analysis and Design Methodology (SSADM) were developed for systems analysis and application design in the UK in the early 80s. Data Flow Diagrams (DFD) are very common and popular nowadays and they are being used in the SSADM method for representing data flows in the information system (IS) and for analysing the data processing during the structural projection. To visualize processes, external entities or data depositories in IS and data flows in order to connect these elements, you can create DFD with help of ConceptDraw DIAGRAM software as well in the application called ConceptDraw STORE where you can find lots of pre-designed samples and templates to make your flowcharts look professional and sophisticated as there are thousands of ready-to-use vector objects developed especially for this purpose. Also you can find many design elements here on our site in the Solutions section. Check for the examples and templates and make your charts look smart and mature even if you had no experience in making them before.

DFD Library System

Context-level Data Flow Diagram or DFD is quite popular in order to show the interaction between the system and external agents which act as data sources and data sinks. Such diagrams help to illustrate the entire system as a single process, and gives no clues as to its internal organization. A System Context Diagram (SCD) defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. Having ConceptDraw DIAGRAM software allows you to make any of mentioned above diagrams as well as create many other diagrams, charts, flowcharts, schemes and plans to be able to have a great looking, very smart, sophisticated and professional result as if you were professional creating all of those flowcharts having any design element you need taken from one of numerous libraries available for our users’ use. Find yourself feeling as if you were a specialist having many years of experience in drawing all of the diagrams we’ve discussed as well as other charts simply having ConceptDraw DIAGRAM tool downloaded to your desktop.
