When formulating a new specific plan, the corresponding buffer time must be added in the middle of the two phases of the new learning knowledge to serve as an example.

(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

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

UMLThe use case diagram is a very useful graph. In demand analysis, it can free people from the heavy documentation, in addition, it prompts people to express their meaning more accurately and intuitively when making demands. Common languagesThe word is often unable to express a thing clearly. At this time, it needs to be expressed in other ways. The example graph is a good method, of course, the use case

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

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

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
