2. Data-flow diagram - Wikipedia

   en.wikipedia.org/wiki/Data-flow_diagram

   Data-flow diagram. 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. A data-flow diagram has no control flow — there are no decision rules and no loops.

3. Sequence diagram - Wikipedia

   en.wikipedia.org/wiki/Sequence_diagram

   This diagram depicts the processes and objects involved and the sequence of messages exchanged as needed to carry out the functionality. Sequence diagrams are typically associated with use case realizations in the 4+1 architectural view model of the system under development. Sequence diagrams are sometimes called event diagrams or event scenarios.

4. Signal-flow graph - Wikipedia

   en.wikipedia.org/wiki/Signal-flow_graph

   A signal-flow graph or signal-flowgraph (SFG), invented by Claude Shannon, [1] but often called a Mason graph after Samuel Jefferson Mason who coined the term, [2] is a specialized flow graph, a directed graph in which nodes represent system variables, and branches (edges, arcs, or arrows) represent functional connections between pairs of nodes ...

5. Process flow diagram - Wikipedia

   en.wikipedia.org/wiki/Process_flow_diagram

   A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations. Another commonly used term for a PFD is ...

6. Algorithmic state machine - Wikipedia

   en.wikipedia.org/wiki/Algorithmic_State_Machine

   An ASM chart consists of an interconnection of four types of basic elements: state name, state box, decision box, and conditional outputs box. An ASM state, represented as a rectangle, corresponds to one state of a regular state diagram or finite state machine. The Moore type outputs are listed inside the box. State Name

7. State diagram - Wikipedia

   en.wikipedia.org/wiki/State_diagram

   The figure below shows a comparison of a state diagram with a flowchart. A state machine (panel (a)) performs actions in response to explicit events. In contrast, the flowchart (panel (b)) automatically transitions from node to node upon completion of activities. [9] Nodes of flowcharts are edges in the induced graph of states.

8. Flow graph (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Flow_graph_(mathematics)

   Flow graph (mathematics) A flow graph is a form of digraph associated with a set of linear algebraic or differential equations: [1][2] "A signal flow graph is a network of nodes (or points) interconnected by directed branches, representing a set of linear algebraic equations. The nodes in a flow graph are used to represent the variables, or ...

9. 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 ...
