Node and artifacts of a system participate in the final execution of a system.Ī deployment diagram plays a critical role during the administrative process, and it must satisfy the following parameters, We can also have node instances on which artifact instances are going to be implemented. It represents the deployment of a system.Ī deployment diagram consists of nodes which describe the physical devices used inside the system.

You can net more than one execution environments in a single device node.įollowing is a representation of an execution environment in UML: execution environment node How to draw a deployment diagram?ĭeployment diagram visualizes the topological view of an entire system. We can nest an execution environment into a device node. JVM is considered as an execution environment for Java applications. For example, Java applications are executed in java virtual machine (JVM).

It is a node that represents an environment in which software is going to execute. In the UML model, you can also nest one or more devices within each other.įollowing is a representation of a device in UML: device node It is represented using a node with stereotype >. It is a node that represents a physical machine capable of performing computations. Generally, a node has two stereotypes as follows: Nodes help to convey the hardware which is used to deploy the software.Īn association between nodes represents a communication path from which information is exchanged in any direction. It is denoted by a 3D box with the node-name written inside of it.

Node is an essential UML element that describes the execution of code and the communication between various entities of a system. A node may vary in its size depending upon the size of the project. A node is a physical thing that can execute one or more artifacts. Node is a computational resource upon which artifacts are deployed for execution. Generally, an artifact instance is represented as follows in the unified modeling language. Each physical copy or a file is an instance of a unique artifact. UML diagram allows this to differentiate between the original artifact and the instance. An artifact instance is denoted with same symbol as that of the artifact except that the name is underlined. artifact Artifact InstancesĪn artifact instance represents an instance of a particular artifact. Generally, an artifact is represented as follows in the unified modeling language. It may be dependent on one another.Īrtifacts have their properties and behavior that manipulates them. An artifact can contain another artifact. Artifacts are labeled with the stereotype >, and it may have an artifact icon on the top right corner.Įach artifact has a filename in its specification that indicates the physical location of the artifact. It can provide physical manifestation for any UML element. The most common artifacts are as follows,Īrtifacts are deployed on the nodes. You can use the artifact to describe a framework which is used during the software development process or an executable file. Deployment Diagram Symbol and notations Deployment Diagram NotationsĪ deployment diagram consists of the following notations:Īn artifact represents the specification of a concrete real-world entity related to software development. It is used to describe software to hardware interaction and vice versa. It visualizes how software interacts with the hardware to execute the complete functionality.

An underlined name represents node instances.ĭeployment diagrams are used with the sole purpose of describing how software is deployed into the hardware system.

It contains node instance, the relationship between node instances and artifact instance.

It contains nodes, the relationship between nodes and artifacts.

There are two forms of a deployment diagram. Many nodes are involved in the deployment diagram hence, the relation between them is represented using communication paths. The software systems are manifested using various artifacts, and then they are mapped to the execution environment that is going to execute the software such as nodes. In distributed systems, it models the distribution of the software across the physical nodes. The deployment diagram maps the software architecture created in design to the physical system architecture that executes it. It maps software pieces of a system to the device that are going to execute it. It also determines how the software is deployed on the underlying hardware. Deployment Diagram is a type of diagram that specifies the physical hardware on which the software system will execute.
