Data Flow Diagram (DFD)

A Data Flow Diagram (DFD) illustrates the flow of data through an information system, visualizes how the information is handled in terms of inputs and outputs, how the data enter to system and leave it. It is effective to use a Data Flow Diagram for creation the system's overview, to show the system's scope and boundaries. There are two different types of notations for DFDs: Yourdon-Coad and Gane-Sarson, which differ in visual representations for processes, data flow, data stores, external entities, etc. Thus, for example the processes are depicted as circles in Yourdon-Coad notation and as rounded squares in Gane-Sarson notation. Gane-Sarson notation is usually used for visualization information systems and Yourdon-Coad - for system analysis and design. The Data Flow Diagrams solution included to Software Development area of ConceptDraw Solution Park offers a lot of DFD templates, samples and examples, libraries of vector stencils for construction without efforts the DFDs according to both Gane-Sarson and Yourdon-Coad notations.

DFD Library — Design elements

Data Flow Diagrams (DFD) solution from the Software Development area of ConceptDraw Solution Park provides plenty of predesigned templates, samples and DFD vector design elements proposed by three DFD libraries. These DFD library objects are designed to help you effectively model the data flows and functional requirements for the business processes or systems, to design the Process-oriented models or Data-oriented models, Data flowcharts and Data process diagrams, Structured analysis diagrams and Information flow diagrams. There are two different notations used to draw the Data Flow Diagrams (Yourdon & Coad and Gane & Sarson). These notations define the different visual representations for the processes, data stores, data flows, and external entities. ConceptDraw DIAGRAM software provides you with possibility of designing professional-looking Data Flow Diagrams, DFD Models, Data Flow Process Diagrams using any of these notations. Simply drag the predesigned DFD flowchart symbols from the appropriate library and connect by arrows depicting the data flow from one step to another.

Interior Design. Plumbing — Design Elements

The plumbing system is a complex system of water supply pipes and drainpipes, sanitary equipment and drainage facilities, vent pipes and more. It supplies our homes, offices, hospitals, schools, business centers, and many other buildings with the main product for life - a water. For effective planning and montage the plumbing equipment, you need obligatory create and use different schematics of plumbing systems, the annotated plumbing diagrams, water lines and waste water plans. These diagrams are an obligatory part of any building project. They are used at all stages - construction, finishing works, interior design, and also during the exploitation of premises in cases of occurence some problems. Numerous libraries offered by the Plumbing and Piping Plans solution from Building Plans area of ConceptDraw Solution Park contain vector objects of plumbing components, sanitary equipment, bathroom fixtures, and many more for easy design the Plumbing and Piping plans, schematic diagrams and blueprints for hot and cold water supply systems, and waste water disposal systems.
