UML is a modeling specification in the software industry, which can establish a requirement model, a design model, an implementation model, and a test model for software projects, because UML has accurate modeling semantics and can be effectively integrated between various models, so it can be simulated and verified based on the model, so that the design has complete forward-looking capabilities.

The latest UML specification is 2.5, which has 13 types of diagrams, divided into 2 categories: static structure diagrams and dynamic behavior diagrams. UML is more professional and abstract to learn because of the accuracy of modeling, here is a special snake game as an example to explain the 13 kinds of UML diagrams, as shown in the following figure:
