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. The flowchart shows the steps as boxes of various kinds, and their order by connecting the boxes with arrows.
Activity diagrams are constructed from a limited number of shapes, connected with arrows. [4] The most important shape types are as follows: stadia represent actions; diamonds represent decisions; bars represent the start (split) or end (join) of concurrent activities; a black circle represents the start (initial node) of the workflow;
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.
A Message Flow is represented with a dashed line, an open circle at the start, and an open arrowhead at the end. It tells us what messages flow across organizational boundaries (i.e., between pools). A message flow can never be used to connect activities or events within the same pool. Association An Association is represented with a dotted line.
Swimlane diagrams first appeared in the 1940s as a variation of the flow process chart called multi-column charts. [1] They were called Swim Lane diagrams by Geary Rummler and Alan Brache in their book Improving Performance (1990). They were first introduced to computer-based diagramming by iGrafx. Swimlanes are also known as "Rummler-Brache ...
Flow diagram is a diagram representing a flow or set of dynamic relationships in a system. The term flow diagram is also used as a synonym for flowchart , [ 1 ] and sometimes as a counterpart of the flowchart.
Flow control: This is a control concept applied to workflows, to distinguish from static control of buffers of material or orders, to mean a more dynamic control of flow speed and flow volumes in motion and in process.
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.
