Software Quality assurance and testing (Job five)

deployment Diagram ( tasks assigned to the project this week)

I. Introduction to the deployment diagram

The deployment diagram is used to describe the structure of the system at runtime, showing how the hardware is configured and how its software is deployed to the network architecture. From the deployment diagram, we can learn about the physical relationships between software and hardware components.

Ii. composition of the deployment diagram

1. Junction points

A node, usually described as a three-dimensional box, consists of two small rectangles sticking out of a rectangle. Typically it represents a computing device.

2. Node instances

The node instance name format is the following node Instance:node, which differs from the node in that the name has an underscore and a colon before the node type.

3. Components

Component (Component) is a simple encapsulation of data and methods. Simply put, a component is a repeatedly used object that has a specific function.

4. Connect

The link between the nodes is the connection. It is the path that represents the interaction in the system.
