Ein Sequenzdiagramm (englisch sequence diagram) ist ein Verhaltensdiagramm, welches eine Interaktion im Sinne der Unified Modeling Language (UML) grafisch darstellt. Im Rahmen der UML, einer Modellierungssprache für Software und andere Systeme, ist das Sequenzdiagramm eine von vier Interaktionsdiagrammarten.

Sequence Diagrams - Pearson HE UK Figure 4.1 is a sequence diagram that shows one implementation of that sce-nario. Sequence diagrams show the interaction by showing each participant with a lifeline that runs vertically down the page and the ordering of messages by reading down the page.

A sequence diagram is a form of interaction diagram which shows objects as lifelines running down the page, with their interactions over time represented as messages drawn as arrows from the source lifeline to the target lifeline. Sequence diagrams are good at showing which objects

Sequence Diagrams What is a Sequence Diagram? • A model describing how groups of objects collaborate in some behavior over time. • The diagram captures the behavior of a single use case. • It shows objects and the messages that are passed between these objects for the particular use case.

(Find an example sequence diagram with an option fragment in the Sequence Diagram Templates and Examples section). Loops . Loop fragment is used to represent a repetitive sequence. Place the words 'loop' in the name box and the guard condition near the top left corner of the frame. Interaction, Collaboration, Sequence Diagrams with EXAMPLES Sequence diagrams can be easily updated according to the changes within a system. Sequence diagram allows reverse as well as forward engineering. Drawbacks of a sequence diagram. Sequence diagrams can become complex when too many lifelines are involved in the system. If the order of message sequence is changed, then incorrect results are produced. PDF System Sequence Diagrams - GitHub Pages System Sequence Diagram | A system sequence diagram (SSD) illustrates input and output events. •An SSD shows - for one particular scenario of a use case - • the events that external actors generate, • their order, and • inter-system events •The system is treated as a black-box •SSDs are derived from use cases; SSDs are often

UML Sequence Diagrams are interaction diagrams that detail how operations are carried out. They capture the interaction between objects in the context of a collaboration. Sequence Diagrams are time focus and they show the order of the interaction visually by using the vertical axis of the diagram to represent time what messages are sent and when.
