Sinsing analysis of the deployment diagram of UML modeling

First, the concept of a deployment diagram

The so-called deployment diagram, translated into English is Deployment Diagram, which is used to display the system software and hardware physical architecture. From the deployment diagram, we can learn about the physical relationships between software and hardware components and the distribution of the components of physical nodes. The deployment diagram enables you to display the structure of the runtime system, while also conveying the configuration and deployment of the hardware and software elements that make up your application.

Second, the use of the deployment diagram

After the completion of the software, the physical topology of hardware and software is drawn out, and the deployment and environment of the system are clearly explained. With the deployment diagram, the relevant personnel of the system can know which hardware the software should be installed on.

Third, the composition of the deployment diagram

The deployment diagram consists of two parts: node and relationship. Some deployment diagrams also contain artifacts, but the artifacts must be on the nodes that correspond, rather than being isolated.

iv. Explanation of the deployment diagram

(1) Node: the common name of the compute resource. Includes processors and devices. Where the processor is the hardware structure that can execute the program, such as computers and servers. A device is a service that is performed externally through an interface, such as a printer. Each node should give the appropriate tag description, such as operating system, vendor, and so on. It can be represented by a cubic rectangle, which is a shaded cube, and the device is a cube without shading.

(2) Relationship: mainly includes the dependency relationship and the correlation relation. Also, we should specify the name of the link between nodes when drawing relationships. For example, servers and clients are connected over a local area network.

Five, the drawing process of the deployment diagram

(1) Identify the individual nodes of the system to be plotted and determine the node

(2) Find out the communication relationship of each node

(3) Draw the deployment diagram, each node must have a name, indicating the name of the physical contact between the nodes
