objects. Code is not a member of a class, but a parameter or local variable of its method. Aggregate (... owns ...), combination (... is a part ...), are associated (... has ...). However, Association tends to be the relationship with two independent and equal things, such as a good friend or a good friend. However, aggregation and combination tend to be the relationship between the whole and the part. The difference between aggregation and combination lies in the overall grasp of some lifecycl

Various diagrams in UML are an important part of the UML model. In recent articles, I will introduce nine important diagrams in UML. The general content is shown in the following directory. 1. use case diagram, class diagram, and object Diagram 2. Sequence diagram and collab

UML includes nine types of diagrams: use case diagram, class diagram, object diagram, component diagram, deployment diagram, activity diagram, collaboration diagram, state diagram, and sequence diagram. Using Case, class, and sequence diagrams in these diagrams is the most useful.Based on the intention, you can divide

ObjectivePrevious "Functional Programming Primer classic", wordy long, many small partners see foggy. Here is an example of how functional programming is fascinating and interesting. Of course, there is no point in writing code just for example, and the example provided in this book is a specific project or tool that takes on a task, which is naturally not the exception.This book uses a lot of UML class diagram, often have small partners asked me what

What is *modelgoon? It is an Eclipse plug-in for model design based on UML diagrams and reverse engineering (that is, from an existingSourcegenerate class diagrams, etc. for code analysis or document use). * Applicable conditionsModelgoon Current version is 3.0.0 for eclipse3.4+, including the latest version of Eclipse 3.6* How to installrecommended online instal

the participant, it can be considered a generalization relationship. The generalization relation is the inheritance relation between the general class and the special class. Cars and ships, for example, have a generalized relationship with transportation. They belong to the same means of transport, with their own characteristics.Use cases and use cases: there are generally generalizations, inclusions (uses), and extensions.Use case generalization: a use case can be specifically enumerated as on

(notification circuit).5. There is an aggregation relationship between the re-insured notification and the Plan library. Because the plan library can be entered in advance, and the re-insurance notification is not necessarily linked, can exist independently. In the system is manually selected from the list. Delete the re-insurance notification without affecting the plan.6. There is an aggregation relationship between the cut notification and the demand order. Similarly, a demand order can exist

, you should have a clear understanding of the system to be constructed. Although this work can be completed step by step while writing code, it is also very attractive, but the efficiency of collective discussion with graphics and text is much higher. It is often not that cost-effective to write detailed requirements for a website. However, you should have time to draw several sketches and write several annotations to describe the services the websit

Drawing a class diagram is a very troublesome thing. If there are tools to automatically generate class diagrams, then how good! A simple search, there really is. As (2.1) below a plugin code iris can be generated automatically.1 Plug-in installationInstallation is simple, as below find plugin, search code iris, and then install, restart as a bit, it can be used.2 useRight-click the module, click Generate Graph, and in the left tab you can find the cl

the interface of the component implementation. The introduction of interfaces is the interface used by the components. Six, the significance of the component diagram(1) The source code is modeled, it can be divided into several modules or subsystems to be processed.(2) Modeling the relationships between executables, which can clearly describe the dependencies between executables. Seventh, the drawing of component drawing(1) To determine the external interface of the subsystem, the process subsy

1. Turn from: http://blog.sina.com.cn/s/blog_5bd6b4510101585x.htmlWhen drawing class diagrams in Visio, we generally need to draw interfaces and implementation classes and indicate their implementation relationships . But for a long while did not realize the relationship, only the generalization relationship (inheritance relationship), how to do? In fact, it is very simple, as follows:First step:

The knowledge of UML has been learned for a while, and the understanding of the nine types of diagrams has changed a lot since I did not understand it before. The viewpoint on pure theoretical knowledge of software engineering has also changed, it tastes a little bit better. In my opinion, the nine diagrams of UML are

From: 51testing software testing ForumUML includes nine types of diagrams: use case diagram, class diagram, object diagram, state diagram, sequence diagram, collaboration diagram, activity diagram, component diagram, and configuration diagram. 1) use case diagram is the simplest and most complex diagram in UML. Simply put, it is because it adopts the object-oriented idea and is based on the user's perspecti

that draw dots, boxes, and text strings on character-based grids that involve many Java object-oriented concepts and applications that are very systematic and comprehensive, and will quickly master UML class diagrams After you have studied them. and apply it to the actual Java application development process. To reduce the length of the code to make the program

Introduction The learning of UML started on the 3rd and ended on the evening of the 13th. Today (Nov 14), I reviewed UML and refined the following learning tasks. The overall learning of UML is similar, but there are still many areas to be improved. Learning Process At the beginning of UML learning, I first spent half

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 diagram. Draw a clean

-oriented analysis and design, it also supports the entire process of software development starting from requirement analysis. In the system analysis stage, we generally use UML to draw a lot of diagrams, including the use case diagram, status diagram, class diagram, and activity diagram.Diagram, sequence diagram, collaboration diagram, build diagram, and configu

This time I pretended to be drawing on a grid (in fact, this is the built-in feature of many Computer-Aided System Engineering (CASE) tools ), then, you only need to draw boxes and lines like on the grid. Figure 5. clean version of Figure 4 Avoid chaotic or complex GraphsAn image that shows too many details or looks messy does not look very good. It is best to have several pictures that show details of various d

There are many tools for painting class diagrams. I have learned how to use staruml to draw class diagrams. However, this tool is used in Java. For vs programming C ++, I personally feel that Using Visio is better. The following uses a block class in the previous Tetris game as an example to describe it. 1 class block2 {3 public:4 block (void );5 void Init (); //
