The Application Model consists of nodes and their properties. Nodes can have child nodes, and they form the tree structure of the Application Model. This topic explains how the Application Model structure for a particular application is formed.
应用程序模型有节点和他的属性组成。节点有子节点，他们构成了应用程序模型。这个主题介绍如何定制一个应用程序模型。
The Application Model tree structure is defined via interfaces derived from the IModelNode interface. The basic structure is described by the base IModelApplication interface. This interface defines the root Application node, its properties and child nodes. To implement specific functionality, Modules and Controllers extend the Application Model with additional interfaces. When an application is started, all the interfaces that define and extend the Application Model are collected from code. Then, an object implementing all these interfaces is compiled. This object represents the actual Application Model. So, depending on the Modules and Controllers used in an application, the Application Model structure can vary.
应用程序模型是通过继承IModelNode接口的接口实现。由基础IModelApplication接口描述基本架构。这个接口定义应用程序的根节点及他的属性和子节点。为了实现特定功能，模块和控制器扩展应用程序模型用其它接口。当启动应用程序是，从代码中收集定义和扩展应用程序模型的所有接口信息。然后，一个对象实现编译所有哪些接口。这个对象代表实际应用程序模型。因此，在模块和应用程序中使用控制器的不同，应用程序模型的结构可以有所不同。
When implementing a custom Module or a Controller, you can extend the Application Model, if required. To learn how to do this, refer to the Extend and Customize the Application Model in Code help topic.
如果需要，你可以自定义一个模块和控制器扩展应用程序模型。学习如何实现，请参考用代码扩展和自定义应用程序模型帮助主题。
The following sections describe the interfaces extended by extra modules shipped with XAF, and lists the extending interfaces.
