  1. This document describes UML versions up to UML 2.5 and is based on the corresponding OMG™ Unified Modeling Language™ (OMG UML®) specifications. UML diagrams were created in Microsoft® Visio® 2007-2016 using UML 2.x Visio Stencils.

The sequence diagram example below shows the interactions between a user and a ticket booking system in booking a seat. It consists of mainly four parts: The actor, which is the user, the boundary object ‘interface', the controller object ‘mainController' and two entity objects routes and route. Enable the UML shape library. Click 'Shapes' in the upper-left corner of the editor, and once you're in the Shape Library Manager, select 'UML' and click 'Save.' Because the shapes in a communication diagram are the same as a sequence diagram, make sure you have the UML sequence diagram shapes enabled.

UML2 has considerably improved sequence diagrams. It is now possible to:

Example Of Sequence Diagram Uml

  • reference other UML sequence diagrams,
  • represent loops and choices,
  • define formal and current call parameters (gates), and so on

Modelio sequence diagrams support all these powerful features, and provide a set of smart interactions that make modeling even easier.

How to find location through ip address. Just drag and drop a class into a sequence diagram to create a lifeline, or drag and drop an interaction into a sequence diagram to create an interaction reference with all its gates.

The vector stencils library 'UML sequence diagrams' contains 50 symbols for the ConceptDraw PRO diagramming and vector drawing software.

If the lifeline is that of an object, it demonstrates a role. Note that leaving the instance name blank can represent anonymous and unnamed instances.
Messages, written with horizontal arrows with the message name written above them, display interaction. Solid arrow heads represent synchronous calls, open arrow heads represent asynchronous messages, and dashed lines represent reply messages. If a caller sends a synchronous message, it must wait until the message is done, such as invoking a subroutine. If a caller sends an asynchronous message, it can continue processing and doesn’t have to wait for a response. Asynchronous calls are present in multithreaded applications and in message-oriented middleware. Activation boxes, or method-call boxes, are opaque rectangles drawn on top of lifelines to represent that processes are being performed in response to the message (ExecutionSpecifications in UML).
Objects calling methods on themselves use messages and add new activation boxes on top of any others to indicate a further level of processing.
When an object is destroyed (removed from memory), an X is drawn on top of the lifeline, and the dashed line ceases to be drawn below it (this is not the case in the first example though). It should be the result of a message, either from the object itself, or another.
A message sent from outside the diagram can be represented by a message originating from a filled-in circle (found message in UML) or from a border of the sequence diagram (gate in UML).' [Sequence diagram. Wikipedia]
