Activity Diagram Object Flow
Object flow is a path along which objects or data can pass.
Activity diagram object flow. See uml superstructure specification v2 1 1 figure 12 110 p 391. Here is a detailed article on uml activity diagrams. The control flow is drawn from one operation to another. This flow can be sequential branched or concurrent.
Activities modeled can be sequential and concurrent. The actions coordinated by activity models can be initiated because other actions finish executing because objects and data become available or because some events external to the flow occur. This explicit portrayal of the data object order connected to the activities by two object flows can be refined by using this format. An object is shown as a rectangle.
An activity diagram is particularly good at expressing the flow of objects matter energy or data through a behavior with a focus on how the objects can be accessed and modified in the execution of that behavior during system operation. They can also describe the steps in a use case diagram. An object flow is shown as a connector with an arrowhead denoting the direction the object is being passed. Common usages of an activity diagram in sysml includes.
Activity diagram is basically a flowchart to represent the flow from one activity to another activity. An object flow is a path along which objects or data can pass. An object flow must have an object on at least one of its ends. Activity diagram is uml behavior diagram which shows flow of control or object flow with emphasis on the sequence and conditions of the flow.
The activity can be described as an operation of the system. Here action pins are used to reflect the order. Activity diagrams are often used in business process modeling. In activity diagrams there are several ways to define the flow of data between objects.
Thus it is typically used to specify behavior with a focus on the flow of control and the transformation of inputs into outputs through a sequence of actions. It describes the system activities or the person who does the activity and the sequential flow of these activities.
