Abstract

A method for facilitating application development, the method including 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 method further includes passing the page token 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. The method further includes applying business logic to contents of the page token as a result of the passing, and presenting a response to the request based upon results of applying the business logic.
