  2. Data-flow diagram - Wikipedia

    en.wikipedia.org/wiki/Data-flow_diagram

    The data-flow diagram is a tool that is part of structured analysis and data modeling. When using UML, the activity diagram typically takes over the role of the data-flow diagram. A special form of data-flow plan is a site-oriented data-flow plan. Data-flow diagrams can be regarded as inverted Petri nets, because places in such networks ...

  3. Activity diagram - Wikipedia

    en.wikipedia.org/wiki/Activity_diagram

    Activity diagrams are graphical representations of workflows of stepwise activities and actions [1] with support for choice, iteration, and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the ...

    A functional flow block diagram ( FFBD) is a multi-tier, time-sequenced, step-by-step flow diagram of a system 's functional flow. [2] The term "functional" in this context is different from its use in functional programming or in mathematics, where pairing "functional" with "flow" would be ambiguous. Here, "functional flow" pertains to the ...

  6. Data-flow analysis - Wikipedia

    en.wikipedia.org/wiki/Data-flow_analysis

    Data-flow analysis is a technique for gathering information about the possible set of values calculated at various points in a computer program. A program's control-flow graph (CFG) is used to determine those parts of a program to which a particular value assigned to a variable might propagate. The information gathered is often used by ...

  7. Data model - Wikipedia

    en.wikipedia.org/wiki/Data_model

    Data-Flow Diagram example. 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).

  8. 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, so that the order of instruction execution ...
