Activity Diagram Vs Sequence Diagram

The following are the difference between activity and sequence diagrams. A sequence diagram shows the way of processes execute in a sequence.

How To Remove The Message Numbers In Sequence Diagram

Sequence diagram is mainly used to represent the time order of a process.

Activity diagram vs sequence diagram. 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. Uml state machine diagram and activity diagram are both behavioral diagrams but have different emphasesactivity diagram is flow of functions without trigger event mechanism state machine is consist of triggered states. With smartdraw you can create more than 70 different types of diagrams charts and visuals.

A typical workflow can be repersented by activity diagram while sequence diagram is more about exploring into use case by showing intercation between objects. While sequence diagram is used to dynamic modeling purpose. State diagrams versus flowcharts.

Sequence diagram is used to describe the behavior of several objects in a single use case. For activity diagram using swimlanes make sure the start point is placed in the. The figure below shows a comparison of a state diagram with a flowchart.

A sequence diagram is focused to represent interactions between different objects. Activity diagram is used to represent the execution of the process. For example the order of operations and the parameters.

Activity diagrams is used to describe the general sequence of actions for several objects and use cases. The main difference between activity diagram and sequence diagram is that the activity diagram represents the flow of activities one after the other in a system while the sequence diagram represents the sequence of messages flowing from one object to another. Activity diagram shows the actions for various objects.

The main difference between activity diagram and flowchart is that activity diagram is a uml behavior diagram that represents the workflow of stepwise activities of the system while flowchart is a graphical diagram that represents the sequence of steps to solve a problem. A small filled circle followed by an arrow represents the initial action state or the start point for any activity diagram. People often confuse state diagrams with flowcharts.

Activity diagram is uml behavior diagram which shows flow of control or object flow with emphasis on the sequence and conditions of the flow. An activity diagram depicts the operational workflows. Activity diagram also repersents an object role in workflow like sequence diagram but level of repersenation.
