I’ve also used a drum as a visual stereotype for the University DB database, making it easier to distinguish on the diagram. Figure 1 presents composxnt example of a fully rendered UML 2 deployment diagram for the student administration application.
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:. The information contained in Figure 2 can just as readily be captured in either a network diagram or a free-form eiagramme in combination with installation scripts. 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.
In short, you may want to consider xiagramme a deployment diagram for all but the most trivial of systems.

As always, it depends on your goals. Gabays uml 2 analyse et conception pdf home ebooks. Identify the scope of the model.
How robust does your system need to be will there be redundant hardware to failover to? More important, practice has shown that deployment modeling is well worth it. They are used to illustrate the structure of arbitrarily complex systems. Les participants n ont pas besoin d etre explicitement declares. 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 composan opinion.
The unified modeling language reference manual temida. Get uml 2 analyse et conception pdf phrontisteria library. UML 2 deployment diagram for the diagarmme information system. 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.
How secure does the system need to be do you need a firewall, do you need to physically secure hardware, and so forth? This is particularly true when you are modeling an environment consisting xiagramme a many interconnected machines. It likely doesn’t matter anyway, because the modeling tool s that you’re using likely won’t fully support the current version of the UML notation perfectly anyway.
Will your application have two tiers, three tiers, or more? Se indiquent quun composant client depend dune certaine maniere dun composant fournisseur. Composabt nodes should be labeled with the stereotype deviceto indicate that it’s a physical device such as a computer or switch.
In this case the software artifact is a fictional persistence framework purchased from AmbySoft the vendor is indicated with a UML property string. Does the diagram address how to deploy a version of a single application or does it depict the deployment of all systems within your organization?
Very often less-detailed network diagramswhich are arguably deployment diagrams with extensive use of visual stereotypes, are a better option.
Deployment specifications are basically configuration files, such as an EJB deployment descriptor, which define how a node should operate. The notation may have evolved from when I originally developed the diagrams. Remember, diagtamme models don’t need to be perfect, they need to be just barely good enough.
In unified modeling language uml, a component diagram depicts how components are wired together to form larger components or software systems.
A better example is shown in Figure 2. The three-dimensional boxes represent nodes, either software or hardware. Sometimes a high-level free-form diagram is a better option because the notation is much more flexible. Another difference is that the concise version shows less details, not as many tagged values are shown as this information can be captured in either supporting documentation, configuration files, or source code.
Deployment diagrams can also be created to explore the architecture of embedded systems, showing how the hardware and software components work together. To determine whether you need to create a deployment model, ask yourself this: Scribd is the worlds largest social reading and publishing site. They are depicted as two-sectioned rectangles with the stereotype deployment specthe top box indicates the name and the bottom box lists the deployment properties if any for the node.
Deployment models force you to think about important deployment issues long before you must deliver the actual system. Your distribution strategy will define the general type of nodes you will have, but not the exact details.
