  2. Data-flow diagram - Wikipedia

    en.wikipedia.org/wiki/Data-flow_diagram

    A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system). The DFD also provides information about the outputs and inputs of each entity and the process itself. A data-flow diagram has no control flow — there are no decision rules and no loops.

  3. Data-flow analysis - Wikipedia

    en.wikipedia.org/wiki/Data-flow_analysis

    A canonical example of a data-flow analysis is reaching definitions. A simple way to perform data-flow analysis of programs is to set up data-flow equations for each node of the control-flow graph and solve them by repeatedly calculating the output from the input locally at each node until the whole system stabilizes, i.e., it reaches a fixpoint.

  4. Structured analysis - Wikipedia

    en.wikipedia.org/wiki/Structured_analysis

    A data flow diagram (DFD) is a graphical representation of the "flow" of data through an information system. It differs from the system flowchart as it shows the flow of data through processes instead of computer hardware. Data flow diagrams were invented by Larry Constantine, developer of structured design, based on Martin and Estrin's "data ...

    en.wikipedia.org/wiki/Data_model

    Data-Flow Diagram example [19] A data-flow diagram (DFD) is a graphical representation of the "flow" of data through an information system. It differs from the flowchart as it shows the data flow instead of the control flow of the program. A data-flow diagram can also be used for the visualization of data processing (structured design).

  6. Dataflow programming - Wikipedia

    en.wikipedia.org/wiki/Dataflow_programming

    A pioneer dataflow language was BLOck DIagram , published in 1961 by John Larry Kelly, Jr., Carol Lochbaum and Victor A. Vyssotsky for specifying sampled data systems. [9] A BLODI specification of functional units (amplifiers, adders, delay lines, etc.) and their interconnections was compiled into a single loop that updated the entire system ...

  7. Flowchart - Wikipedia

    en.wikipedia.org/wiki/Flowchart

    Common alternative names include: flow chart, process flowchart, functional flowchart, process map, process chart, functional process chart, business process model, process model, process flow diagram, work flow diagram, business flow diagram. The terms "flowchart" and "flow chart" are used interchangeably. The underlying graph structure of a ...

  8. Enterprise modelling - Wikipedia

    en.wikipedia.org/wiki/Enterprise_modelling

    Store: Data-collection or some sort of material. Flow: Movement of data or material in the process. External Entity: External to the modelled system, but interacts with it. Now, with these symbols, a process can be represented as a network of these symbols. This decomposed process is a DFD, data flow diagram.

  9. Dataflow architecture - Wikipedia

    en.wikipedia.org/wiki/Dataflow_architecture

    Dataflow architecture is a dataflow-based computer architecture that directly contrasts the traditional von Neumann architecture or control flow architecture. Dataflow architectures have no program counter, in concept: the executability and execution of instructions is solely determined based on the availability of input arguments to the instructions, [1] so that the order of instruction ...
