Step by step UML modeling Series 2. Deployment Diagram)

Overview

A deployment diagram (deployment divisor) is used to display the physical architecture of software and hardware in the system. From the deployment diagram, you can understand the physical relationship between software and hardware components and the component distribution of processing nodes. The deployment diagram shows the structure of the runtime system and the configuration and deployment modes of the hardware and software elements that constitute the application.

A uml deployment diagram (Object Management Organization 2001) describes a runtime hardware node and a static view of software components running on these nodes. The deployment diagram shows the system hardware, software installed on the hardware, and middleware used to connect heterogeneous machines. The purpose of creating a deployment model is as follows:

· Explore issues related to system production.
· Explore the dependencies between your system and other systems in the production environment. These systems may already exist or will be introduced.
· Describe the main deployment structure of a commercial application.
· Design the hardware and software structure of an embedded system.
· Describe the hardware/network infrastructure of an organization.

 

Deployment dimo-elements)

 

1. Node)

A node is a physical element that represents computer resources during existence and operation. It can be a hardware or software system running on it, such as a 64 host, a Windows server 2008 operating system, or a firewall. The node is represented in a three-dimensional box, such:

 

2. Node Instance)

Node instance name format:Node Instance: node

The difference with a node is that the name has an underline and a colon Before the node type, and there can be an example name or no sample name before the colon, as shown in

 

3. Artifact)

Objects are the product of software development, including process models (such as use case diagrams and design drawings), source code, executable programs, design documents, test reports, requirement prototypes, and user manuals. The object is represented as follows, with the keyword "artifact" and the document icon

4. Connection)

The connection between nodes indicates the communication path for interaction between systems. This communication path is called Association, as shown in
