41 in A Sequence Diagram, The _____ Indicates When An Object Sends Or Receives A Message.

UML Sequence Diagrams - CODE Mag The Sequence Diagram is one of the most interesting and useful diagrams in the Unified Modeling Language (UML). It helps you document and understand the dynamic aspects of your software system - specifically the sequence of messages that are sent and received between objects. Sequence Diagram - Visual Paradigm Interaction diagrams address the dynamic view of a system. A sequence diagram is an interaction diagram that emphasizes the time-ordering of messages. It depicts the objects and classes involved in the scenario and the sequence of messages exchanged between the objects needed to carry out the functionality of the scenario.

What is Sequence Diagram? - Visual Paradigm 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.

Lifelines in UML diagrams - IBM In UML diagrams, such as sequence or communication diagrams, lifelines represent the objects that participate in an interaction. For example, in a banking scenario, lifelines can represent objects such as a bank system or customer. Each instance in an interaction is represented by a lifeline. Lifelines in sequence diagrams Sequence Diagram Tutorial - Complete Guide with Examples When an object sends a message to itself, it is called a reflexive message. It is indicated with a message arrow that starts and ends at the same lifeline as shown in the example below.
