Design Data Flow. DFD Library

Data flow diagram or DFD is a type of diagrams used for graphical representation the "flow" of data through an information system, for effective modeling its process aspects and for visualization the data processing. They are one of the best tools for clearly making an overview of the system that will be developed, for depiction in details what kinds of information will be inputted to the system and outputted from it, where they will be stored, and other details. ConceptDraw PRO software with Data Flow Diagrams solution from Software Development area of ConceptDraw Solution Park is powerful in a field of designing the DFDs. Three libraries containing 49 vector DFD shapes and symbols are offered by Data Flow Diagrams (DFD) solution. Use them to design data flow diagrams, information flow diagrams, data flowcharts, data process diagrams, structured analysis diagrams, to create the data-oriented models or process-oriented models, and so on. Pay also attention for the included collection of DFD samples, examples and built-in templates at ConceptDraw STORE. Read more

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 PRO 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. Read more

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.

Flowchart

The Flowcharts are widespread in various fields and include the multitude of types. They are dedicated to representation the algorithms, processes, workflows of any complexity in a clear and intuitive format. The Flowcharts are commonly used in software development as a visual tool for illustration algorithms and logic of computer programs, in business for illustration business scenarios, in education, and so on. For drawing the Flowchart are used the special object blocks, among them rectangle or box used to represent an activity or step, rounded box or oval to depict Start / End, diamond to represent the decision point (involves the branching yes/no), circle used to represent the point of connection, parallelogram to represent the Input / Output, and some others. With ConceptDraw PRO including Flowcharts solution it is easy to create professional-looking Flowchart diagrams of any complexity and any degree of detailing. Succeed in drawing the Flowcharts using quick-start templates, predesigned samples and extensive libraries of ready-made flowchart symbols, blocks and icons. Read more

This DFD sample was created on the base of figure illustrating the "Interactive Double Mass Analysis. User's Guide" from the website of the Office of Hydrologic Development of the National Weather Service (NWS) of the National Oceanic and Atmospheric Administration (NOAA).
"Double mass analysis is a technique commonly employed to determine corrections to hydrometeorological data to account for changes in data collection procedures or other local conditions. The changes may result from a variety of things including changes in instrumentation, changes in observation procedures, or changes in gage location or surrounding conditions. The purpose of this Interactive Double Mass Analysis (IDMA) tool is to provide an effective and efficient way for users to perform consistency checking using double mass analysis and to produce the correction factors that are used in subsequent processing by NWSRFS preprocessor tools to account for any discovered inconsistencies.
Computations of mean areal time series for use in calibration and ESP have traditionally been made using the appropriate preprocessing software (MAP, PXPP, MAT etc.). The preprocessors have traditionally taken point time series as input and have provided facilities for estimation of missing data, and for consistency checking and correction in addition to the mean areal computations. The IDMA tool has been designed to run in conjunction with the preprocessors in an iterative fashion. It performs the consistency checking function, leaving the estimation, correction and mean areal computations to the preprocessors. ...
As shown in Figure ... the preprocessor software generates a data file that contains accumulated data values for each station and the associated group base, as well as flags indicating whether the values were estimated or not. This data file along with the input card file used by the preprocessor are used by the IDMA tool. The IDMA tool then allows the user to perform consistency checks and to calculate correction factors. The correction factors are then returned so that the preprocessors can perform the corrections, re-estimate missing data and perform the mean areal computations. Note that there is an interdependence between the estimation of missing values in the preprocessors and the correction factors computed in the IDMA and so there needs to be iteration between the two processes until the user is satisfied that an appropriate balance has been reached."
