Component diagram, English name Yue: Component diagrams is used to describe the organization and dependencies between a set of artifacts, for the static implementation view of a modeling system, which can be executable programs, libraries, tables, files, and documents, and includes implementation information for logical classes or logical classes. Therefore, there is a mapping relationship between the structure model view and the implementation. Component diagrams can also include or subsystem,

Package diagrams is a combination of model elements that are represented in UML in a notation similar to a folder, each element in the system can be owned by only one package, one package can be nested in another, and a package diagram can be used to classify the related elements into a system that contains a package, chart, or individual element. In simple terms, we can directly understand the package as a namespace, a folder, is used to organize the

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.

In the nine diagrams of UML, the class and object graph are static graphs, and the reaction is the static process of the system. The class diagram is described earlier, and the following is the object graph. One, the object graph summary Two: Object Graph example The object graph is concrete, and the class diagram is abstract. such as the admin class in the class diagram. The straight line object belongs to the shape class and consi

The main purpose of this article is to continue to focus on the basic UML diagram. This month, we will learn more about the sequence diagram. Note that the following example is based on the new UML 2 Specification. Purpose A Sequence Chart is used to display the interaction between objects in a series of order of interaction. Like a class chart, developers generally think that a sequence chart is only meani

Unified Modeling Language (UML) defines a series of standard symbols for describing object-oriented systems. Use UML to enhance communication between domain experts, workflow experts, software designers, and other experts from different backgrounds. UML can be used in common situations and is intuitive to the users of the workflow system. In addition to these,
