Recently in the use of State mode to write a simulated Windows Calculator MFC program, the way to learn the UML diagram drawing, especially class diagram and state diagram of the drawing, here to summarize it.I. INTRODUCTION of UMLUnified Modeling Language UML (abbreviation for Unified Modeling language): is a standard language used for visual modeling of software systems.(1) in the development stage,

The first contact with UML was last year, when Liu Lijia teacher taught for us, because there was no specific project, so the UML Course is not very important, I think most people should be the same as I do UML did not give enough attention, this semester we opened the software requirements analysis This course, and let me re-contact

This year, Apple's iPhone 4 and iPad continued to be quite successful. More and more developers in China wanted to develop software on Apple's platform to make money. What UML modeling tools are available for software development on Apple's platform? Although there are not as many tools as can be selected on the Windows platform, some of them can be listed. Mac platform native UML modeling tools, the most p

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, uniied Modeling Language ). There are nine types of modeling icons in UML: Use case diagram Class Diagram Object Graph Sequence Chart Collaboration Diagram Status chart Activity diagram Component Diagram Configurat

Summary This article analyzes the architecture mode of web applications and introduces the UML extension mechanism to model various objects in Web applications. This paper discusses the UML modeling and development methods for Web applications under the. NET Framework and applies them to a practical management system. The actual application shows that this method can reduce the development complexity, short

I entered school in September and graduated in July. It ended my pleasant and rich college life at the Software Institute. This series is a review of the four-year study of professional courses, see: http://blog.csdn.net/xiaowei_cqu/article/details/7747205UML is short for Unified Modeling Language (Unified Modeling Language.

Most software developers know UML, but how can UML play a major role in software project development? The following describes the special features of different phases of the project. The special requirements of the situation refer to the use of UML. Application of UML in different stages of software: I. Demand an

In the previous article "UML System Analysis and Design 02-use case diagram and activity diagram (I)", we mainly explained the use case analysis and drawing methods and techniques in requirement analysis, however, the use case diagram only tells us what the system wants to do. As for how to do it, there is no intuitive description. To better illustrate how our system meets user needs one by one, and provide users with detailed descriptions of "how to

UML Reference Manual Part 1 Background Chapter 1 nature and objectives of the ModelThis chapter explains what a model is, how it is used, and how to use it. This chapter also explains the different layers of the model: Ideal, partial, and tool-based.2.1 What is ModelA model is an expression of similar or other tools using a certain tool. Models start from a modeling point of view and grasp the most important

1. Introduction to UML UML (Unified Modeling Language) is a visual modeling language that is well defined, easy to express, powerful, and universally applicable. It integrates new ideas, new methods, and new technologies in the software engineering field. Its scope is not limited to supporting object-oriented analysis and design, but also supporting the entire process of software development starting from r

We have learned some knowledge and content of UML. The following is a brief summary of UML. 1.1 What is UML 1.1.1 a visual Object-Oriented Modeling Language1.1.2 describes the dynamic behavior of a system's static structure1.1.3 graphical representation of the entire structure of a typical object-oriented system1.1.4 model the system from different angles and fo

these things from the UML's defined building blocks, create a new building block by using stereotypes to specify these new semantics and to give a distinctive visual cue. If you want to distinguish these things from the build modules defined in UML, you can create a new build module by using the model, it is used to describe these new semantics and provide a unique visualized mark. 3. If the thing you are modeling is some kind of hardware that itsel

. "When" is the answer, that is, how the development work is scheduled; 4. "Who" means that some development (or maintenance) work is intended to be done by "who? "· 5. "How" means how certain requirements are met; 6. Why? The above is the relevant content of the soft work document. Let's take a look at the relationship between the UML diagram and the document below: First, the UML diagram does not corre

In my study of design patterns, I used UML for modeling.At first I was not too clear on the understanding of the various relations, on the internet also searched some information, now on the class diagram of these kinds of relationships: dependency, association, aggregation, composition, generalization, implementation of a description.First of all, we need to know two points:1. Order of their relationships: generalization = implementation > Compositio

UML use case Diagrams: guidelines Released: 2012-3-21 In Visual Studio flagship edition, you can draw a use case diagram to summarize the users of your application or system and the purpose of the application or system. To create a UML use case diagram, on the Architecture menu, click New Diagram.Use case diagrams help yo

Read the "UML War Needs analysis," the beginning of "nonsense", I deeply feel the rigor of UML senior users and comprehensive.First, the first part-"Why should I write this book"-is the goal in the software requirements analysis. The modesty language is fascinating, tells us "uses the UML" is the key, through the actual combat ability to truly grasp the

Article Source: http://www.cnblogs.com/duanxz/archive/2012/06/13/2547801.htmlThe ways in which the relationships between objects and classes are described in UML include: Dependency (Dependency), Association (association), Aggregation (Aggregation), composition (composition), generalization (generalization), Implementation (realization) and so on. Dependent ( Dependency ): The change of element a affects element B, but the other is not, so the rel

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 diagram is not only dedicated for demand analysis, but also powerfulLarge applicability can

: Network Disk DownloadEditorial recommendationsThe editor's book reflects the author's experience of structuring systems and teaching software engineering courses for over more than 10 years. We find that students often study programming techniques and software engineering techniques in isolation, often choosing small problems as examples. The result is that students are able to effectively address well-defined issues, but often feel helpless when they first truly face complex and real developm
