The notation may have evolved from when I originally developed the diagrams.

How do you intend to monitor the system once it has been deployed? Remember, models evolve over time. The UML evolves over time, and I may not have kept the diagrams up to date. Remember, agile models don’t need to be perfect, they need to be just barely good enough. When determining how comppsant model the deployment architecture for a system, regardless of the artifacts chosen, I will typically: A better example is shown in Figure 2.
Dependances indiquent quun composant client depend dune certaine maniere dun composant fournisseur. Diagramme de composant notion de port bonjour, je suis en train d effectuer des recherches sur les diagrammes de composant en uml et je viens de dcouvrir la notion de port et je n arrive gref bretagne trouver un lieu d information et l.
Your distribution architecture strategy will often be predetermined for your application, particularly if you are deploying your system diagrzmme an existing technical environment.

When you stop and think about it, the stereotypes that I’ve applied to the connections aren’t correct. Although this would be more accurate it would be a lot of work that I likely wouldn’t get much benefit from. Physical nodes should be labeled with the stereotype deviceto indicate that it’s a physical device such as a computer or switch. If you’re really concerned about the nuances of “official” UML notation then read the current version of the UML specification.
Deployment diagrams can also be created to explore the architecture of embedded systems, showing how the hardware and software components work together.
I’ve also used a drum as a visual stereotype for the University DB database, making it easier to distinguish on the diagram. 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.
Scribd is the worlds largest social reading and publishing site.
The software components use the same notation as component diagrams I could have annotated them with their interfaces although that wouldn’t have added any value in my opinion. Consider fundamental technical issues.
Identify the nodes and their connections. Very often less-detailed network diagramswhich are arguably deployment diagrams with extensive use of visual stereotypes, are a better option. Identify the scope of the model. 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? Get uml 2 analyse et conception pdf phrontisteria library.
In my opinion the deployment properties is superfluous as this fiagramme the type of information that is contained in the actual deployment specification file at run time. The unified modeling language reference manual temida. In reality the software on the web server is communicating via the RMI protocol over the connection to the software on the application server.
This is so far the most comprehensive book on uml 2. The unified modeling language reference manual james rumbaugh, ivar jacobson, grady booch. 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.
The ApplicationServer node contains EJBContainer a software node which in turn contains three software components, a deployment specification, and composxnt software artifact. Software elements are now simply listed by their physical filenames, information that developers are very likely to be interested in, and thus a more compact diagram is possible.
Both versions of the deployment diagrams indicate the software that is deployed on each node, critical information for anyone involved in development, installation, or operation of the composany.
UML 2 Deployment Diagrams: An Agile Introduction
The notation used in these diagrams, particularly the hand drawn ones, may not conform perfectly to the current version of the Conposant for one or more of reasons:.
When you think about it installation scripts are effectively “deployment source code”. How secure does the system need to be do you need a firewall, do you need to physically secure hardware, and so forth?
As always, it depends on your goals. Nodes can contain other nodes ce software artifacts. 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. UML 2 deployment diagram for the university information system. Identify the distribution architecture. I’d also need to model a dependency relationship between the software connection and the hardware connection, perhaps with the stereotype of over.
When determining how to model the deployment um2 for a system, regardless of the artifacts chosen, I will typically:. Diagramme global dinteraction interaction overview diagram.
How agile are deployment diagrams? More important, practice has shown that deployment modeling is well worth it. Will your application have two tiers, three tiers, or more?
In this case the diavramme artifact is a fictional persistence framework purchased from AmbySoft the vendor is indicated with a UML property string.
Connections between nodes are represented with simple lines, and are assigned stereotypes such as RMI and message bus to indicate the type of connection. To determine whether you need to create a deployment model, ask yourself this: You need to make platform decisions, such as vomposant hardware and operating systems to be deployed, including how the various nodes will be connected perhaps via RMI and a message bus as in Figure 2.
They are used to illustrate the structure of arbitrarily complex systems. duagramme
In short, you may want to consider creating a deployment diagram for all but the most trivial of systems. An agile modeler is more interested in created models which communicate effectively than in conforming to notation rules set by a committee.
