connected to the end of the arrow and the arrow points to the parent use case. 7. The difference between extended and inclusive relationships Same point: is a relationship between two use cases. (Only a generalization relationship can represent two use cases, or it can be between two participants) different points: conditionality: An extended relationship that contains an unconditional relationship is a conditional insertion principle: The event stream that contains the use case must be insert

Actionactions (Actions) in a UML state diagram are an executable atomic operation, which means that the action is non-interruptible and its e

The text simply lists a few simple grammatical rules that take advantage of the various views made by PLANTUML. You can see that PLANTUML provides a very simple syntax rule that provides a convenient way for users to edit.PLANTUML offers many ways to edit languages, such as TXT text, Html,java,c/c++,latex,apt,word

PrefaceIn the summary of the UML state diagram, the activity diagram and the state diagram are closely related. It also has a lot in common with flowcharts.definitionAn activity diagram is a special form of a state diagram. All or

The main purpose of this article is to continue to focus our emphasis on the basic UML diagram; This month, we learn more about sequence diagrams. Again, please note that the example provided below is based on the new UML 2 specification. The purpose of the diagram Sequence diagrams are primarily used to display these

different roles in Figure 14. Note that you cannot create a class role in a pure class diagram, even if figure 18 shows you can. To use the role mark, you will need to use the internal structure mark discussed below. Internal StructureOne of the more useful functions of the UML 2 structure diagram is the new internal structure mark. It allows you to show how a c

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

This section describes the issues that should be avoided when creating a clean UML diagram. I believe you will be familiar with the methods for creating a clean UML diagram through this article, let's take a look at how to draw a clean UML

Abstract: this is an article about the unified modeling language, that is, the basic diagram used in UML. In this article, I will discuss the structure diagram, which is a new graph type that has been proposed in UML 2. Since the purpose of this series of articles is to help people understand the mark elements and thei

first, the definition: Time series diagrams (Sequence Diagram), also known as sequence or sequential plots, are UML behavior diagrams. It shows the dynamic collaboration between multiple objects by describing the chronological order in which messages are sent between objects. It can represent the sequence of behavior of a use case, and when a routine is performed, each message in a sequence

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.

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 inter

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

Classes (Class) A rectangular box is used in UML to represent a class. Class diagram is divided into three layers, the first layer displays the class name, and if it is an abstract class, it is shown in italics. The second layer is the attributes of the class, usually the fields and properties. The third layer is the operation of the class, usually the method or the behavior. Note the preceding symbol, ' +

In the 13 graphs of UML 2.0, class diagrams are one of the most frequently used UML diagrams. Martin Fowler in his book "UML Distilled:a Brief Guide to the Standard object Modeling Language, Third Edition" (UML Essence: A concise reference to the model language South (3rd edition)) There is a paragraph in this: "If som

Objectiveclass diagrams and sequence diagrams are two of the most commonly used diagram in UML. I will make a detailed summary. In many books, or Web sites, when introducing the design of a subsystem of a system, many times, a simple class diagram is given to describe the relationship between the classes that make up the subsystem. This is sufficient to illustrat
