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. Use case diagram - Wikipedia

   en.wikipedia.org/wiki/Use_case_diagram

   A use case diagram [1] is a graphical depiction of a user's possible interactions with a system. A use case diagram shows various use cases and different types of users the system has and will often be accompanied by other types of diagrams as well. The use cases are represented by either circles or ellipses. The actors are often shown as stick ...

4. Control-flow diagram - Wikipedia

   en.wikipedia.org/wiki/Control-flow_diagram

   A flow diagram can be developed for the process [control system] for each critical activity. Process control is normally a closed cycle in which a sensor . The application determines if the sensor information is within the predetermined (or calculated) data parameters and constraints.

5. N2 chart - Wikipedia

   en.wikipedia.org/wiki/N2_Chart

   The diagram is complete when the user has compared each entity to all other entities. The N2 diagram should be used in each successively lower level of entity decomposition. Figure 1 illustrates directional flow of interfaces between entities within an N 2 diagram. (In this case, the entities are functions.)

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. Dataflow programming - Wikipedia

   en.wikipedia.org/wiki/Dataflow_programming

   The flow of data is explicit, often visually illustrated as a line or pipe. In terms of encoding, a dataflow program might be implemented as a hash table, with uniquely identified inputs as the keys, used to look up pointers to the instructions. When any operation completes, the program scans down the list of operations until it finds the first ...

8. Functional flow block diagram - Wikipedia

   en.wikipedia.org/wiki/Functional_flow_block_diagram

   Figure 1: Functional flow block diagram format. [1] 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 ...

9. Control-flow graph - Wikipedia

   en.wikipedia.org/wiki/Control-flow_graph

   In computer science, a control-flow graph (CFG) is a representation, using graph notation, of all paths that might be traversed through a program during its execution. The control-flow graph was conceived by Frances E. Allen , [ 1 ] who noted that Reese T. Prosser used boolean connectivity matrices for flow analysis before.
