Abstract: Application development is facilitated by initializing a page token in response to receiving a request. The page token comprises an abstract model component containing a specification for obtaining data designated to be sent in a response to the request or a specification for updating data obtained from the request, and also a view component for providing referential format specifications for data provided in the abstract model component. The page token is passed between at least two components of a modified model-view-controller architecture via a standard interface. The components include a user interface controller, a user interface builder implementing a first standard interface, an application layer implementing a second standard interface, a data access manager implementing a third standard interface, and at least one data access utility implementing a fourth standard interface.
