    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.

    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. Function model - Wikipedia

    Store: Data-collection or some sort of material. Flow: Movement of data or material in the process. External Entity: External to the modeled 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. Example of functional decomposition ...

  8. Functional flow block diagram - Wikipedia

    en.wikipedia.org/wiki/Functional_flow_block_diagram

    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.

  9. Activity diagram - Wikipedia

    en.wikipedia.org/wiki/Activity_diagram

    Activity diagrams can be regarded as a form of a structured flowchart combined with a traditional data flow diagram. Typical flowchart techniques lack constructs for expressing concurrency. [ 5 ] However, the join and split symbols in activity diagrams only resolve this for simple cases.
