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 related activities.
The process (function, transformation) is part of a system that transforms inputs to outputs. The symbol of a process is a circle, an oval, a rectangle or a rectangle with rounded corners (according to the type of notation). The process is named in one word, a short sentence, or a phrase that is clearly to express its essence. [7] Data flow
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. The reason is that each node in a flowchart represents a program command.
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. Here, "functional flow" pertains to the sequencing of operations, with "flow" arrows expressing dependence on the success of prior operations.
DRAKON was created as an easy to learn visual language to aid the comprehension of computer programs written in different programming languages for illustrative, planning and strategy purposes. DRAKON uses drakon-chart, which is a formalization of traditional flowcharts to depict the overall structure of the program.
As such it forms the core technique for modeling in ARIS, which serves to link the different views in the so-called control view. To quote from a 2006 publication on event-driven process chains: [2] An Event-driven process chain (EPC) is an ordered graph of events and functions. It provides various connectors that allow alternative and parallel ...
The term flow diagram is used in theory and practice in different meanings. Most commonly the flow chart and flow diagram are used in an interchangeable way in the meaning of a representation of a process. For example the Information Graphics: A Comprehensive Illustrated Reference by Harris (1999) gives two separate definitions:
