2. Data-flow diagram - Wikipedia

   en.wikipedia.org/wiki/Data-flow_diagram

   Data flow diagram with data storage, data flows, function and interface. 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.

3. N2 chart - Wikipedia

   The five functions are on the diagonal. The arrows show the flow of data between functions. So if function 1 sends data to function 2, the data elements would be placed in the box to the right of function 1. If function 1 does not send data to any of the other functions, the rest of the boxes to right of function 1 would be empty.

   A screenshot of the flowchart software Flowgorithm. Any drawing program can be used to create flowchart diagrams, but these will have no underlying data model to share data with databases or other programs such as project management systems or spreadsheet. Many software packages exist that can create flowcharts automatically, either directly ...

5. Control-flow diagram - Wikipedia

   en.wikipedia.org/wiki/Control-flow_diagram

   Control and data are most applicable for real time and data-driven systems. These flow analyses transform logic and data requirements text into graphic flows which are easier to analyze than the text. PERT, state transition, and transaction diagrams are examples of control-flow diagrams. [4]

6. 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.

7. Functional flow block diagram - Wikipedia

   Each FFBD shall contain the following contextual and administrative data: [9] Date the diagram was created; Name of the engineer, organization, or working group that created the diagram; Unique decimal delimited number of the function being diagrammed; Unique function name of the function being diagrammed. Figure 8 and Figure 9 present the data ...
