Which components are used in a Web Dynpro Application to transport database data to the user interface?

In a Web Dynpro application, the context node plays a crucial role in transporting database data to the user interface. The context node serves as a key structural element that holds the application’s data model, enabling communication between the backend and the frontend.

When data is fetched from the database, it is populated into the context nodes. These nodes encapsulate the data in a structured manner, allowing developers to manage the data effectively through attributes, aggregations, and associations. Once the context nodes are populated with data, they make this information available to the user interface for display and interaction. This allows the Web Dynpro application to present dynamic, data-driven content that responds to user actions.

This mechanism of utilizing context nodes ensures a clear separation between data handling and presentation, aligning with the development principles of Web Dynpro that promotes reusability and maintainability of the components in the application.
