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.
