RETRIEVING DATA FOR GENERATING VIEW COMPONENTS

摘要

A user interface with a main controller and subcontrollers nested within the main controller. The main controller refers to blueprint tables to instantiate and manage the subcontrollers. The subcontrollers are responsible for generating view components displayable in client devices. The main controller receives requests from client devices and manages the communications between subcontrollers, and between a subcontroller and a model of business data and logic. One or more subcontrollers and their respective views may form a container for data management on the screen. The main controller assembles the views from the subcontrollers into a page and transmits it to the client device. A user interface builder for defining blueprint tables is also disclosed.
