Activity Diagram Object Flow
Activity diagram is uml behavior diagram which shows flow of control or object flow with emphasis on the sequence and conditions of the flow.
Activity diagram object flow. Here is a detailed article on uml activity diagrams. Activity diagram is similar to a business work flow diagram or simply a flowchart with much richer semantics. Here action pins are used to reflect the order. It describes the system activities or the person who does the activity and the sequential flow of these activities.
An object flow must have an object on at least one of its ends. This explicit portrayal of the data object order connected to the activities by two object flows can be refined by using this format. See uml superstructure specification v2 1 1 figure 12 110 p 391. The activity can be described as an operation of the system.
An activity diagram visually presents a series of actions or flow of control in a system similar to a flowchart or a data flow diagram. The control flow is drawn from one operation to another. This flow can be sequential branched or concurrent. An object is shown as a rectangle.
Object flow is a path along which objects or data can pass. Common usages of an activity diagram in sysml includes. An object flow is a path along which objects or data can pass. This diagram depicts a simple object flow between two actions fill order and ship order both accessing order information.
Activity diagram is basically a flowchart to represent the flow from one activity to another activity. An object flow is shown as a connector with an arrowhead denoting the direction the object is being passed. They can also describe the steps in a use case diagram. Activity diagrams are often used in business process modeling.
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. 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.
