  2. Data-flow diagram - Wikipedia

    en.wikipedia.org/wiki/Data-flow_diagram

    For each data flow, at least one of the endpoints (source and / or destination) must exist in a process. The refined representation of a process can be done in another data-flow diagram, which subdivides this process into sub-processes. The data-flow diagram is a tool that is part of structured analysis and data modeling. When using UML, the ...

    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.

  5. Control-flow diagram - Wikipedia

    en.wikipedia.org/wiki/Control-flow_diagram

    A control-flow diagram (CFD) is a diagram to describe the control flow of a business process, process or review. Control-flow diagrams were developed in the 1950s, and are widely used in multiple engineering disciplines. They are one of the classic business process modeling methodologies, along with flow charts, drakon-charts, data flow ...

  6. Structured data analysis (systems analysis) - Wikipedia

    en.wikipedia.org/wiki/Structured_data_analysis...

    Structured data analysis (SDA) is a method for analysing the flow of information within an organization using data flow diagrams.It was originally developed by IBM for systems analysis in electronic data processing, although it has now been adapted for use to describe the flow of information in any kind of project or organization, particularly in the construction industry where the nodes could ...

  7. Workflow - Wikipedia

    en.wikipedia.org/wiki/Workflow

    In scientific experiments, the overall process (tasks and data flow) can be described as a directed acyclic graph (DAG). This DAG is referred to as a workflow, e.g., Brain Imaging workflows. [23] [24] In healthcare data analysis, a workflow can be identified or used to represent a sequence of steps which compose a complex data analysis. [25] [26]

  8. Process flowsheeting - Wikipedia

    en.wikipedia.org/wiki/Process_flowsheeting

    Process design then proceeds on the basis of the flow sheet chosen. Physical property data are the other component needed for process design apart from a flow sheet. The result of process design is a process flow diagram, PFD. Detailed engineering for the project and vessel specifications then begin. Process flowsheeting ends at the point of ...

  9. Flowchart - Wikipedia

    en.wikipedia.org/wiki/Flowchart

    A simple flowchart representing a process for dealing with a non-functioning lamp.. A flowchart is a type of diagram that represents a workflow or process.A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task.
