a dynamic diagram that shows the activity and the event that causes the object to be in the particular state
a flowchart-like diagram describing the flow of control from activity to activity
a graph in which the nodes represent activities and the arrows represent transitions between activities
a special case of a state diagram in which all (or at least
a special form of a state diagram in which the states represent the performance of actions or sub-activities and the transitions are triggered by the completion of the actions or sub-activities
a special type of state chart diagram that emphasizes the flow from activity to activity
a visual representation of any system's activities and flows of data or decisions between activities
a UML diagram that models the activity (workflow) of a portion of a software system
A graphic presentation of all or part of an IDEF0 activity model. Three possible types include Node Tree, Context Diagram, Decomposition Diagram.
One of the models supported by the Unified Modelling Language (UML), an activity diagram provides a view of dynamic activity flows in a system. An activity diagram can show parallel behaviour.
A glorified flowchart that shows the steps and decisions and parallel operations within a process, such as an algorithm or a business process.
Contains the top-level function being mapped and its inputs, controls, and mechanisms along with statements of the map’s purpose and viewpoint. A single activity may represent an entire process that is being mapped.
Activity diagrams represent the business and operational workflows of a system. An Activity diagram is a variation of the state diagram where the "states" represent operations, and the transitions represent the activities that happen when the operation is complete.
A special case of a state diagram in which all or most of the states are action states and in which all or most of the of the transitions are triggered by completion of actions in the source states. Contrast: state diagram.
In the Unified Modeling Language, an activity diagram represents the business and operational step-by-step workflows of components in a system. An Activity Diagram shows the overall flow of control.
