Activity Diagram Vs Sequence Diagram

They are used in conjunction with activity diagrams. System sequence diagrams are used to define the input and outputs and sequence of interaction between the user and the system for a use case.

What Is Communication Diagram

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.

Activity diagram vs sequence diagram. A sequence diagram typically shows the execution of a particular use case for the application and the objects as in instances of a class that are involved in carrying out that use case. Difference between statechart and sequence diagram. Typically activity diagrams are used to model workflow or business processes and internal operation.

A sequence diagram shows the way of processes execute in a sequence. The activity diagram or the sequence diagram. Sequence diagrams typically show the interaction between classes instances of those classes and the method calls with arguments.

Sequence diagram models the sequential logic ordering of messages with respect to time. Activity diagram also repersents an object role in workflow like sequence diagram but level of repersenation. For example the order of operations and the parameters.

The following are the difference between activity and sequence diagrams. People often confuse state diagrams with flowcharts. One thought on difference between sequence diagram sd.

A typical workflow can be repersented by activity diagram while sequence diagram is more about exploring into use case by showing intercation between objects. The figure below shows a comparison of a state diagram with a flowchart. While sequence diagram is used to dynamic modeling purpose.

A sequence diagram is focused to represent interactions between different objects. An activity represents an operation on some class in the system that results in a change in the state of the system. An activity diagram depicts the operational workflows.

In sequence diagramstheres information flow in and out of a system are called messages. State diagrams versus flowcharts. The information shown in an activity diagram is known earlier in a project and is independent of things like technology choice which may change how you consider the items shown in a sequence diagram.
