foreword
The main content of this blog is to show the component diagrams and deployment diagrams that I have drawn. So not much to say, I hope this diagram can help some people to understand UML.
component diagram
what
Describe the dependencies between various software components
My understanding is that the charging system client is source code dependent.
constitute
It is easy to see that the representation of the component diagram is a rectangle with two small rectangles inserted on the left.
It is very vividly expressed that this is an interface, so the component is the actual object that can be replaced. That is to say, it does not depend on entities, but interfaces.
UML graphics
This picture is imitated by other great gods, because I am not so clear about the component diagram. Hope to learn more in the future.
Deployment diagram
what
English: deployment diagram
is used to display the physical architecture of software and hardware in the system
Function : to understand the physical relationship between software and hardware components and the distribution of components of processing nodes
UML graphics
The following is the UML diagram I drew. It feels like a gourd drawing, but I got the knowledge myself.
postscript
I have roughly understood these two pictures, and I will learn a lot in the future, and the steps cannot stop at the front~
