Web Dynpro Model 

Definition

Web Dynpro technology is based on the Model-View-Controller concept, which ensures a clear division between the definition of the user interface and the implementation of the application logic. Within this concept, the model retrieves the application data from the back end. For a Web Dynpro application, at least one model must always be defined. If you want to define multiple models, the model must be bound to the relevant Web Dynpro component that the model is to use.

The data for a Web Dynpro application can originate from different sources. You can

• call and use SAP data from a database using BAPIs
• define new data
• combine the two above procedures
• import an external model using the appropriate tools

For more detailed information about the model and binding a controller context to a model, see the following unit in the developers manual: Web Dynpro Model.
