They are used to illustrate the structure of arbitrarily complex systems. The unified modeling language reference manual james rumbaugh ivar jacobson grady booch addisonwesley an imprint of addison wesley longman, inc. Although these diagrams were thoroughly reviewed for the book, and have been reviewed by thousands of people online since then, an error may have gotten past of us. Remember, agile models don’t need to be perfect, they need to be just barely good enough.
I may have gotten it wrong in the first place. The physical connection between the physical hardware nodes is at a lower level, perhaps an Ethernet connection, so in reality I really should have modeled a connection between the hardware nodes with Ethernet as a stereotype and a second connection between software elements with the RMI stereotype.
Diagramme global dinteraction interaction overview diagram. Nodes can contain iml2 nodes or software artifacts.
Software artifacts are shown with the visual stereotype of a page with a folded corner or with the textual stereotype diaramme or both sometimes, which I also believe is superfluous.
To determine whether you need to create a deployment model, ask yourself this: As always, it depends on your goals. The unified modeling language reference manual james rumbaugh, ivar jacobson, grady booch. More important, practice has shown that deployment modeling is well worth it. When you think about it installation scripts diagramke effectively “deployment source code”.
The UML evolves over time, and I may not have kept the diagrams up to date. Identify the distribution architecture.
Your distribution strategy will define the general type of nodes you will have, but not the exact details. I never draw deployment diagrams following the style show in Figure 1except when I’m writing about deployment modeling, because in my opinion this notation is visually wasteful.
I may have chosen to apply the notation in “non-standard” ways. A UML 2 deployment diagram depicts a static view of the run-time configuration of processing nodes and the components that run on those nodes. The ApplicationServer node contains EJBContainer a software node which in turn contains three software components, a deployment specification, and a software artifact.

A better example is shown in Figure 2. I’ve also used a drum as a visual stereotype for the University DB database, making it easier to distinguish on the diagram. Consider fundamental technical issues. The three-dimensional boxes represent nodes, either software or hardware. Although this would be more accurate it would be a lot of work that I likely wouldn’t get much benefit from. Dependances indiquent quun composant client depend dune certaine maniere dun composant fournisseur.
Gabays uml 2 analyse et conception pdf home ebooks. Your distribution architecture strategy will often be predetermined for your application, particularly if you are deploying your system to an existing technical environment. The notation used in these diagrams, particularly the hand drawn ones, may not conform perfectly to the current version of the UML for one or more of reasons:.
Do you intend to take a fat-client approach where the business logic is contained in a desktop application or a thin-client approach where business logic is deployed to an application server? This is particularly true when you are modeling an environment consisting of a many interconnected machines.
Scribd is the worlds largest social reading and publishing site. Deployment models force you to think about important deployment issues long before you must deliver the actual system.
Bottom line is that you’re going to be constrained by your tools anyway. Identify the scope of the model. The unified modeling language reference manual temida. Very often less-detailed network diagramswhich are arguably deployment diagrams with extensive use of visual stereotypes, are a better option. The unified modeling language reference manual, addisonwesley, Physical nodes should be labeled with the stereotype deviceto indicate that it’s a physical device such as a computer or switch.
The software components use the same notation as component diagrams I could diayramme annotated them with their interfaces although that wouldn’t have added any value in my opinion.
Les diagrammes de classes
An agile modeler is more interested in created models which communicate effectively than in conforming to notation rules set by a committee.
You want to create a deployment diagram for applications that are deployed to several machines, for example a point-of-sales application running on a thin-client network computer which interacts with several internal servers behind your corporate firewall or a customer service system deployed using a web services architecture such as Microsoft’s. Connections between nodes are represented with simple lines, and are assigned stereotypes such as RMI and message bus to indicate the type of connection.
Sometimes a high-level free-form diagram is a better option because the notation is much more flexible. Remember, models evolve over time.
