Recently, with the maturity of J2EE, it is becoming

2、a recommendation in the J2EE platform, a design model, the majority of Java developers are also very interested in the design model. MVC model is gradually developed in PHP and ColdFusion are in use, and growth trends. With the rapid increase in web applications, MVC model for the development of Web

3、 applications is a very advanced design idea, no matter what language you choose, no matter how complicated the application, it can be for you to understand and provide the most basic application model analytical methods, structural products for you to provide a clear framework for the design, for y

4、our software projects in accordance with norms.MVC是一种目前广泛流行的软件设计模式，早在70年代，IBM就推出了Sanfronscisico项目计划，其实就是MVC设计模式的研究。近来，随着J2EE的成熟，它正在成为在J2EE平台上推荐的一种设计模型，也是广大Java开发者非常感兴趣的设计模型。MVC模式也逐渐在PHP和ColdFusion开发者中运用，并有增长趋势。随着网络应用的快速增加,MVC模式对于Web应用的开发无疑是一种非常先进的设计思想，无论你选择哪种语言，无论应用多复杂,它都能为你理解分析应用模型时提供最基本的分析方法，为你构造产

5、品提供清晰的设计框架，为你的软件工程提供规范的依据。MVC design ideaMVC in English or Model-View-Controller, an application that is input, process, output process in accordance with the Model, View, Controller isolated manner, such an application is divided into three layers - model layer, view layer, control layer.View （View

6、） on behalf of the user interface for Web applications can be summed up as HTML interface, but has the potential to XHTML, XML, and Applet. With the application of the complexity and scale, the interface has become challenging to deal with. An application may have different views, MVC design pattern

7、 to deal with the view of the limited view of data acquisition and processing, as well as the users request, not included in the view on the handling of business processes. The handling of business processes to the model （Model） to deal with. For example, a view only accept orders from the MVC设计思想MV

8、C英文即Model-View-Controller，即把一个应用的输入、处理、输出流程按照Model、View、Controller的方式进行分离，这样一个应用被分成三个层模型层、视图层、控制层。视图（View）代表用户交互界面，对于Web应用来说，可以概括为HTML界面，但有可能为XHTML、XML和Applet。随着应用的复杂性和规模性，界面的处理也变得具有挑战性。一个应用可能有很多不同的视图，MVC设计模式对于视图的处理仅限于视图上数据的采集和处理，以及用户的请求，而不包括在视图上的业务流程的处理。业务流程的处理交予模型（Model）处理。比如一个订单的视图只接受来自模型的数据并显示给用

9、户，以及将用户界面的输入数据和请求传递给控制和模型。model data and display to users, as well as input user interface data and the request passed to the control and model.Model （Model）: is the business process / status of the processing and business rules. Business process layer is the other black-box operation, the model vie

10、w to accept the request of the data, and return the results of the final. The design of business models can be said to be the most important core of MVC.Currently popular model of EJB applications is a typical example of the application of technology from the perspective of the model further delinea

11、tion in order to make full use of existing components, but it can not be used as a framework for application design model. It only tell you that according to the design of this model will be able to use certain technology components, thereby reducing the technical difficulties. Example of a develper

12、, you can focus on business模型（Model）：就是业务流程/状态的处理以及业务规则的制定。业务流程的处理过程对其它层来说是黑箱操作，模型接受视图请求的数据，并返回最终的处理结果。业务模型的设计可以说是MVC最主要的核心。目前流行的EJB模型就是一个典型的应用例子，它从应用技术实现的角度对模型做了进一步的划分，以便充分利用现有的组件，但它不能作为应用设计模型的框架。它仅仅告诉你按这种模型设计就可以利用某些技术组件，从而减少了技术上的困难。对一个开发者来说，就可以专注于业务模型的设计。MVC设计模式告诉我们，把应用的模型按一定的规则抽取出来，抽取的层次很重要，这也是判断

13、开发人员是否优秀的设计依据。抽象与具体不能隔得太远，也不能太近。model design. MVC design pattern tells us that the application of the model according to certain rules of taking away the level of extraction is very important, which is to determine whether the development in accordance with good design. Abstract and concrete can not

14、 be separated too far, nor too close.MVC model did not provide the design method, but only tell you that the management of these models should be organized in order to facilitate reconstruction and improve the model reusability. We can make an analogy with object programming, MVC defines a top-level

15、 category, the sub-class to tell it you have to do these, but you can not do these restrictions. This is the developer of the programming is very important.There is also a business model of the model is very important that the data model. Data model mainly refers to the object data entities （continued of）.Forexample, an order will be saved to the databaseMVC并没有提供模型的设计方法，而只告诉你应该组织管理这些模型，以便于模型的重构和提高重用性。我们可以用对象编程来做比喻，MVC定义了一个顶级类，告诉它的子类你只能做这些，但没法限制你能做这些。这点对编程的开发人员非常重要。业务模型还有一个很重要的模型那就是数据模型。数据模型主要指实体对象的数据保存（持续化）。
