SAP UI5 MVC Concept - SAP UI5

What is SAP UI5 MVC concept?

Model-View-Controller (MVC) is keep the application data extract from the user interactions. It helps to develop the web applications and make changes to the applications independently.
Model-View-Controller plays a different role in UI development −
  • The Model is responsible for managing the application data in the database/backend.
  • The View is responsible for defining the user interface to users. When a user sends a requests from his device, the view is responsible for data view as per the request submitted.
  • The Controller is used to control the data and view events as per user interaction by updating the view and model.

  • Views are based on Model.

Controller
