A sequence diagram describes the interaction modes between objects in chronological order. It uses the "lifeline" of objects and the messages passed between them to show how objects participate in interaction.

UML consists of nine diagrams, in which the core is the only---class diagram.
Here is my summary of the Class Diagram section in UML.
Class diagram is a static structure that shows the model, especially the classes that exist in the model, the internal structure of the clas
Through the static diagram and behavior diagram introduced in previous blogs, we can use UML to describe the static structure and dynamic behavior of a system. At this time, we have alreadyGraphical representation of the entire structure of a typical Surface-to-face object system.

the relationships between classes
Inheritance Relationship
An inheritance relationship is the most understandable relationship. The picture is like this. The object-oriented argument is the is-a relationship. That is to say Class2 is a Class1. In C + + we say that Class2 is a derived class of Class1, or that Class1 is the base class for Class2.
Aggregation and Composition
Start with a relationship that is easy to understand. There is often a case where a class is a data member of another class.

Label: UMLAn object is a concept, an abstraction or a thing. Objects can be practical or abstract concepts. For example, a company or a process.A class is a set or abstract concept of a group of objects. The class has the same attributes and methods.This section describes the basic concepts of basic objects and classes. It is necessary to describe how to represent objects and classes in UML, that is, how to draw objects and class diagrams. This is jus
