Applications

A Web Dynpro application defines a URL that acts as the client's entry point into the functionality contained within a Web Dynpro Component. That is, a URL is created which points to one of the visual interfaces supplied by a Web Dynpro Component.

The Web Dynpro component is the unit of functionality that acts as the application's entry point. Any component that possesses a visual interface can act as an application entry point, and which ever component has been nominated for this task is known as the root component. The root component should be thought of as being responsible for controlling all further processing that takes place within the application.

A Web Dynpro application cannot exist without there first being at least one Web Dynpro component. In the figure above, the application is shown to contain three components and a model object.
