  2. Flowchart - Wikipedia

    en.wikipedia.org/wiki/Flowchart

    Many software packages exist that can create flowcharts automatically, either directly from a programming language source code, or from a flowchart description language. There are several applications and visual programming languages [ 23 ] that use flowcharts to represent and execute programs.

  3. Data-flow diagram - Wikipedia

    en.wikipedia.org/wiki/Data-flow_diagram

    The process (function, transformation) is part of a system that transforms inputs to outputs. The symbol of a process is a circle, an oval, a rectangle or a rectangle with rounded corners (according to the type of notation). The process is named in one word, a short sentence, or a phrase that is clearly to express its essence. [7] Data flow

  4. Control-flow diagram - Wikipedia

    en.wikipedia.org/wiki/Control-flow_diagram

    In software and systems development, control-flow diagrams can be used in control-flow analysis, data-flow analysis, algorithm analysis, and simulation. Control and data are most applicable for real time and data-driven systems.

  5. Functional flow block diagram - Wikipedia

    en.wikipedia.org/wiki/Functional_flow_block_diagram

    In 1947, ASME adopted a symbol set as the ASME Standard for Operation and Flow Process Charts, derived from Gilbreth's original work. [5] The modern Functional Flow Block Diagram was developed by TRW Incorporated, a defense-related business, in the 1950s. [6]

  6. Process flow diagram - Wikipedia

    en.wikipedia.org/wiki/Process_flow_diagram

    A PFD can be computer generated from process simulators (see List of Chemical Process Simulators), CAD packages, or flow chart software using a library of chemical engineering symbols. Rules and symbols are available from standardization organizations such as DIN, ISO or ANSI. Often PFDs are produced on large sheets of paper.

  7. Activity diagram - Wikipedia

    en.wikipedia.org/wiki/Activity_diagram

    Activity diagrams [1] are graphical representations of workflows of stepwise activities and actions [2] 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 related activities.

  8. Control-flow graph - Wikipedia

    en.wikipedia.org/wiki/Control-flow_graph

    Some CFG examples: (a) an if-then-else (b) a while loop (c) a natural loop with two exits, e.g. while with an if...break in the middle; non-structured but reducible (d) an irreducible CFG: a loop with two entry points, e.g. goto into a while or for loop A control-flow graph used by the Rust compiler to perform codegen.

  9. Warnier/Orr diagram - Wikipedia

    en.wikipedia.org/wiki/Warnier/Orr_diagram

    A Warnier/Orr diagram (also known as a logical construction of a program/system) is a kind of hierarchical flowchart that allows the description of the organization of data and procedures. They were initially developed 1976, [ 1 ] in France by Jean-Dominique Warnier [ 2 ] and in the United States by Kenneth Orr [ 3 ] on the foundation of ...
