Flow chart is a diagrammatic representation of an algorithm and essential part of planning the system. Flow charts are widely used in technical analysis and programming for easy writing programs and explaining them to others. So, one of the most popular type of flow charts is Technical Flow Chart.
Technical Flow Chart can be drawn by pencil on the paper, but it will be easier to use for designing a special software. ConceptDraw DIAGRAM diagramming and vector drawing software extended with Flowcharts Solution from the "Diagrams" Area of ConceptDraw Solution Park will be useful for this goal.
The ConceptDraw Flowchart component includes a set of samples and templates. This geathered as flowchart maker toolbox which focused on drawing flowcharts of any industry standards.
ConceptDraw DIAGRAM extended with Seven Management and Planning Tools Solution from the Management Area of ConceptDraw Solution Park is the best software for drawing all types of diagrams from the Seven Management and Planning Tools: Affinity Diagram, Relations Diagram, Prioritization Matrix, Root Cause Analysis Tree Diagram, Involvement Matrix, PERT Chart, and Risk Diagram (PDPC).
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.
Structured Systems Analysis and Design Method (abbr. SSADM) is a method developed in Great Britain and accepted in 1993 as a national standard for information systems development and analysis. SSADM is based on Data Flow Diagrams and is characterized with presence of clear sequence of steps at projecting, analysis, and documenting of information system. It involves 6 main stages: analysis of existing system or estimation of practicability, requirements definition, determination of technical requirements and equipment cost, development of logical data model, projecting of logical requirements and specification them, physical projecting. Each of them is also divided into several steps defining the tasks that should be fulfilled at a given stage. The most important SSADM elements are flows modeling with help of DFD, data logic modeling with help of LDS (Logical Data Structure) and description of entities behavior.
Applying of SSADM is easy with ConceptDraw DIAGRAM diagramming and vector drawing software and Data Flow Diagram solution.
The business diagrams are in great demand, they describe the business processes, business tasks and activities which are executed to achieve specific organizational and business goals, increase productivity, reduce costs and errors. They let research and better understand the business processes.
ConceptDraw DIAGRAM is a powerful professional cross-platform business graphics and business flowcharting tool which contains hundreds of built-in collections of task-specific vector stencils and templates. They will help you to visualize and structure information, create various Business flowcharts, maps and diagrams with minimal efforts, and add them to your documents and presentations to make them successful. Among them are Data flow diagrams, Organization charts, Business process workflow diagrams, Audit flowcharts, Cause and Effect diagrams, IDEF business process diagrams, Cross-functional flowcharts, PERT charts, Timeline diagrams, Calendars, Marketing diagrams, Pyramids, Target diagrams, Venn diagrams, Comparison charts, Analysis charts, Dashboards, and many more.
Being a cross-platform application, ConceptDraw DIAGRAM is very secure, handy, free of bloatware and one of the best alternatives to Visio for Mac users.
Drawing the diagrams we try to find in help the powerful software and now we have the ConceptDraw DIAGRAM. The ability easily create the SDL diagrams is made possible thanks to unique Specification and Description Language (SDL) Solution from the Industrial Engineering Area of ConceptDraw Solution Park. This solution extends ConceptDraw DIAGRAM libraries - SDL Connectors and SDL Diagrams that contain 70 predesigned SDL flowchart symbols.
Data Flow Diagram (DFD) is a hierarchy of functional processes, connected by data flows. The purpose of this presentation is to show how each process converts its inputs into outputs and to identify relationships between these processes. DFD is convenient way of modeling and construction the information processes, it step-by-step illustrates the flow of information in a process. For construction a DFD traditionally are used two different notations, which appropriate to the methods of Yourdon-Coad and Gane-Sarson. These notations slightly different from each other by graphical representation of symbols for processes, data stores, data flow, external entities. When designing a DFD it is required to decompose the system into the components (sub-systems), for explaining a complex system you may need represent numerous levels.
The Data Flow Diagrams solution from ConceptDraw Solution Park contains numerous predesigned DFD symbols for both notations, which help easy and effectively design professional-looking Data Flow Diagrams (DFDs) and DFD Process Diagrams.
