The lifeline of an object represents a life (over the course of time).

ObjectĪn object represents any object, meaning an undefined object of a class of the IT system: IterationĪn iteration indicates that all objects to which a relationship exists receive the event, for example all the flights of a flight number: Lifeline The goal of the event is to mutate information in the IT system, meaning to create, change, or delete something. Mutation EventĪ mutation event is an event that is sent from the use case, so normally from the user interface, to the IT system: This way, we do not have to decide on one, specific, actor. Since the mutation event that is documented in a sequence diagram can be contained in several use cases, and since these use cases can have different actors, we use the actor somebody: The actor “somebody” represents any actor from the use case diagram. In comments, the flow logic is shown on the topmost level. The flow of a mutation event is documented with a combination of textual description and a sequence diagram: In sequence diagrams, as shown in Figure 4.63, we work with the following elements: Comment The following resources may help you to learn more about the topic discussed in this page.Figure 4.63 The elements of sequence diagrams Drag to the target instance specification and release the mouse button. Press on the Resource Catalog button and drag it out.Move the mouse pointer over the source instance specification.To create link between instance specifications: Click OK again in the Instance Specification Specification window to return to the diagram.Enter the slot value and click OK to confirm.Click Add button and select Text from the pop-up menu.

Perform the steps below to create a UML object diagram in Visual Paradigm. Similar to class diagram, it shows the static design of system from the real or prototypical perspective. Object diagram is a kind of UML diagram that shows a snapshot of instances of things in class diagram.
