I may have chosen to apply the notation in “non-standard” ways. Identify the nodes and their connections. 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.
Nodes can diqgramme other nodes or software artifacts.
diagrammd 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 agile are deployment diagrams? 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.
In reality the software on the web server is communicating via the RMI protocol over the connection to the software on the application server. I’ve also used a drum as a visual stereotype for the University DB database, making it easier to distinguish on the diagram.
When determining how to model the deployment architecture for a system, regardless of the artifacts chosen, I will typically:. Remember, models evolve over time. Although this would be more accurate it would be a lot of work that I likely wouldn’t get much benefit from.
When determining how to model the deployment architecture for a system, regardless of the artifacts chosen, I will typically: More important, composwnt has shown that deployment modeling is well worth it. This is particularly true when you are modeling an environment consisting of a many interconnected machines. If you’re really concerned about the nuances of “official” UML notation then read the current version of the UML specification.
The unified modeling language iml2 manual, second edition if you are a serious user of uml, there is no other book quite like this one. Deployment specifications are basically configuration files, such as an EJB deployment descriptor, which define how a node should operate.
Translations Japanese Disclaimer 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: I may have gotten it wrong in the first place. Deployment diagrams tend to become very large very quickly because they reflect the physical complexities of your system, therefore a concise notation becomes critical to your success.
How robust does your system need to be will there be redundant hardware to failover to? Your distribution viagramme will define the general type of nodes you will have, but not the exact details. When I ask this question of the project teams I work with, we almost always decide to develop some form of deployment model.
Modélisation UML/Les différents types de diagramme
The three-dimensional boxes represent nodes, either software or hardware. An agile modeler is more interested in created models which communicate effectively than in conforming to notation rules set by a committee.
Dependances indiquent quun composant client depend dune certaine maniere dun composant fournisseur. Figure 1 presents an example of a fully rendered UML 2 deployment diagram for the student administration application.
The unified modeling language reference manual james rumbaugh, ivar jacobson, grady booch. 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 system.
Sometimes a high-level free-form diagram is a better option because the notation is much more flexible. In my opinion the deployment properties is superfluous as this is the type of information that is compoaant in the actual deployment specification file at run time.
The unified modeling language reference manual temida.
Software artifacts are shown with the visual stereotype of a page with a folded corner or with the textual stereotype artifact or both sometimes, which I also believe is superfluous. In short, you may want to consider creating a deployment diagram for all but the most trivial of systems.
Exemple complet des guichets automatiques bancaires article suivant exercice uml. 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.
UML 2 Deployment Diagrams: An Agile Introduction
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? The information contained in Figure 2 can just as readily be captured in either a network diagram or a free-form diagram in combination with installation scripts.
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?
Will your application have two tiers, three tiers, or more? I’d also need to model a dependency relationship between the software connection and the hardware connection, perhaps with the stereotype of over. In unified modeling language uml, diagrammr component dixgramme depicts how components are wired together to form larger components or software systems. Get uml 2 analyse et conception pdf phrontisteria library. Bottom um2 is that you’re going to be constrained by your tools anyway.
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. Consider fundamental technical issues. The notation may have evolved from when I originally developed the diagrams. Identify the scope of the model. Deployment diagrams can also be created to explore the architecture of embedded systems, showing how the hardware and software components work together.
