Defining a Sequence diagramĪ sequence diagram is made up of objects and messages. Hence, the Sequence diagram is one of the most widely used dynamic diagrams in UML.

On the horizontal axis, it shows the life of the object that it represents, while on the vertical axis, it shows the sequence of the creation or invocation of these objects.īecause it uses class name and object name references, the Sequence diagram is very useful in elaborating and detailing the dynamic design and the sequence and origin of invocation of objects. This makes the Sequence diagram a very useful tool to easily represent the dynamic behavior of a system.Ī Sequence diagram is two-dimensional in nature. The invocation of methods in each object, and the order in which the invocation occurs is captured in a Sequence diagram. BasicsĪ Sequence diagram depicts the sequence of actions that occur in a system. By the end of this article, you will know what a Sequence diagram is, what its elements are, and, you will be able to create Sequence diagrams for your system. One of the most widely used dynamic diagrams in UML is the Sequence diagram, which is the topic of our discussion today. We then made an Activity diagram for a specific scenario in our Courseware Management system.
