Depicts object interactions over time: show a user or actor, and the objects and components they interact with in the execution of a use case. One sequence diagram typically represents a single Use Case 'scenario' or flow of events
A UML diagram showing the sequence of interactions among objects.
A UML Diagram showing the dynamic behavior as messages are passed between objects. Equivalent to a Collaboration Diagram. Which representation is appropriate depends on the problem under consideration. See Section 4.5, "Sequence Diagrams (To be written)" for more information.
a diagram showing the operations between parts of the system over time
a form of behavioral diagram that enables you to specify the interactions that exist between a set of objects
a form of interaction diagram which shows objects as lifelines running down the page and with their interactions over time represented as messages drawn as arrows from the source lifeline to the target lifeline
a means to illustrate a use case by representing the collaborations between entities from a temporal point of view
a model that describes how groups of objects collaborate in some behavior over time
an easily comprehensible visualization of single scenarios or examples of business processes with regard to their behavior in time
an interaction diagram that emphasizes the time-order of messages
an interaction diagram that focuses on the time-ordering of message s
a structured representation of behavior as a series of sequential steps over time
a type of interaction diagram in the UML
a type of iteration diagram that describes how objects collaborate in some behavior
a UML-standard representation of objects interacting with each other
a visual representation of the interaction between collaborating groups of objects in a system
A diagram that shows the existence of Objects over time, and the Messages that pass between those Objects over time to carry out some behavior.
A sequence diagram is an interaction diagram that details how operations are carried out, what messages are sent and when. Sequence diagrams are organized according to time. The time progresses as you go down the page. The objects involved in the operation are listed from left to right according to when they take part in the message sequence.
A particular sort of UML Interaction Diagram that describes interactions (message passing) among the application's objects. The Sequence Diagram describes a particular sequencing of the messages. Contrast: Collaboration Diagram.
A diagram that shows object interactions arranged in time sequence. In particular, it shows the objects participating in the interaction and the sequence of messages exchanged. Unlike a collaboration diagram, a sequence diagram includes time sequences but does not include object relationships. A sequence diagram can exist in a generic form (describes all possible scenarios) and in an instance form (describes one actual scenario). Sequence diagrams and collaboration diagrams express similar information, but show it in different ways. See: collaboration diagram.
The well-known Message Sequence Chart technique has been incorporated into the Unified Modeling Language (UML) diagram under the name of Sequence Diagram. A sequence diagram shows, as parallel vertical lines, different processes or objects that live simultaneously, and, as horizontal arrows, the messages exchanged between them, in the order in which they occur. This allows the specification of simple runtime scenarios in a graphical manner.
