As a modeling language, the definition of UML consists of UML Semantics and UML notation.(1) UML semantic description precise metadata model definition based on UML. The meta-model provides simple, consistent, and general definitions for all
Maybe you are a newbie, maybe you have never touched UML. Maybe you have heard this word for the first time. It does not matter! Let's explain the UML in cainiao's eyes today. Maybe you have some reference for the first contact with UML. There is a more standardized definition in the Data. "The main achievement of the Research on object-oriented modeling technolo
UML for many people should not be a strange concept, the past two years, the UML has been more and more discussion. It seems that the subject of UML and I do not seem to have much of a relationship (it is language-independent, even if it is in itself a language-for communication). I'm here to talk about it for two purposes: 1.
Before formally designing patterns, it is necessary to introduce the relationship between UML class diagrams, because some tutorials, books, including my post, will use a lot of class diagrams to describe the relationships between the various classes. This is a very intuitive, minimalist way.Of course, the ability and energy are limited, the introduction of the UML here is only limited to a few common inter
In the process of learning UML, you often encounter UML class diagram relationship, here to introduce you to the UML arrows, lines represent the meaning, I believe that through the introduction of this article you have a more explicit understanding of the meaning of arrows and lines in UML.AD:This section to learn about UML
Reprinted: http://jeffrey.blogbus.com/logs/66085.html Chapter 6 public mechanism In the UML introduction in Chapter 2, the common mechanism of UML is mentioned, including Specification Description, modification, General Division and extension mechanism. This chapter details the Modification and extension mechanisms. ① Note)Annotation is a graphical symbol appended to an element or element set to re
The key to dealing with object-oriented problems is modeling. Modeling can abstract many important details in the complex world. Many Modeling tools encapsulate UML (that is, the Unified Modeling Language). This course aims to show the highlights of UML. There are nine types of modeling icons in UML: Use case diagram Class Diagram Object Graph Sequence Chart
UML class diagram Using UML class diagrams, we can express the static content of classes and their relationships. In the class diagram, we can show the member variables and member functions of the class, as well as the inheritance and reference relationships between classes. In short, we can depict all source code-level dependencies between classes. In UML, a cla
Objective The key to successfully using Java EE to build enterprise applications is the same as all complex software platforms: Effective communication of requirements, formulation of correct analysis and design decisions, and identification of the best implementation options. Companies that pursue the best visualization models can develop their software faster and build higher-quality systems. Unified Modeling Language (UML) is a visual modeling so
Design Mode: Why does Java development require UML-general Linux technology-Linux programming and kernel information? For details, see below. Do you know what kind of situation the UML has caused? Do you know what types of functions are available in UML but not in JAVA? Do you know why we need another computer language besides JAVA?
Transferred from: http://www.360doc.com/content/10/1206/23/3123_75672033.shtmlSome time ago participated in the technical lecture of Pangayu teacher, UML modelling technology benefited greatly. I also put some of the usual accumulation and the last harvest summarized in this article, mainly on the use case diagram related knowledge.The use case diagram is the first step in the software requirements analysis to the final implementation, which describes
I. Types of Graphs As a modeling language, the definition of UML consists of UML Semantics and UML notation. (1) UML semantic description precise metadata model definition based on UML. The meta-model provides simple, consistent, and general definitions for all
Above: UML from requirement to design -- use case From the beginning to the present, I have gained a more in-depth understanding of UML. At the beginning, I always felt that UML is a diagram. When I mentioned UML, I thought it was a painting thing. What are these images? Why are these images? In a project, the figu
Content Overview 1. describes the design process of Object-Oriented Analysis Based on UML. 2. What charts and the functions of each diagram are included in the UML object-oriented model? 1. describes the design process of Object-Oriented Analysis Based on UML. 1. Identify system use cases and RolesFirst, conduct a Demand Survey on the project. Based on the busi
UML, as a design tool, focuses on practice, and this is inseparable from nine types of diagrams. drawing is done after watching the video. When I first started to draw a picture, my head was broken, I don't know where to start, so I learned the relationship between the nine images and the four types of graphs again before drawing the picture. I finally got a bit of an idea, this begins to draw. The nine types of U
After learning UML and RUP for a long time, it seems that everything is confusing. Then I began to look for the reason: do you think there are any cool people? Have you received system training? The company does not apply the conditions. For example, the time cannot be used? Is there a lot of companies in China ?...... I attended the Microsoft vs2005 meeting and chatted with the Microsoft Senior friend about support for the development process and mod
I know the unified modeling language. What do I mean? What is the difference with programming languages? Image Description. ========================================================== ============== UML Unified Modeling Language (UML) is a language used for Visual Modeling of software-intensive systems. UML is a standard language used to describe, visualize,
In the previous article, the UML graphic thinking of Architecture Design briefly introduced the graphic thinking design and expressed the importance of design for architects, this section briefly introduces how to use the Unified Modeling Language (UML) to describe classes and the inheritance relationships between classes. This description is still used to write code, next, we will learn to use
YesWhat is the big chaos caused by UML? Do you know what types of functions are available in UML but not in JAVA? Do you know why we need another computer language besides JAVA? UML is not just a substitute for JAVA or other languages. UML is an annotation of object-oriented analysis and design.
the UML, which has been studied for so long, has a certain understanding of UML. Now a small sum, if there are mistakes, I hope you correct me. Learn together and make progress together. "What is UML?" "UML (Unified Modeling Language) Unified Modeling Language, is the standard modeling language for software and sys
