14+ Sequence Diagram Explained. A sequence diagram is a form of interaction diagram which shows objects as lifelines running down the sometimes a sequence diagram will have a lifeline with an actor element symbol at its head. Sequence diagrams share most of the functionalities of normal diagrams, but they have some specificities and restrictions.
The sequence diagram is an interaction diagram of uml. Sequence diagram describes an interaction by focusing on the sequence of messages that are exchanged, along with their corresponding occurrence specifications on the lifelines. What is a sequence diagram?
You create sequence diagrams to display use cases and check systems for logic.
14+ Sequence Diagram Explained. A sequence diagram is a form of interaction diagram which shows objects as lifelines running down the sometimes a sequence diagram will have a lifeline with an actor element symbol at its head. Sequence diagrams show object interactions arranged in a time sequence (refer figure 5.10). Sequence diagrams are a great way for software developers to model interactions between different parts of a system. It depicts the objects involved in the scenario and the sequence of messages exchanged between the objects needed to carry out the functionality of the scenario.
