Method to design the Interaction Controllers of Web pages on a Web Application

  Disclosed is a method to design the Interaction Controllers of Web pages in a Web application.

It describes how to develop Controller components based on the Model-View-Controller (MVC) design paradigm. It does not describe how to create interactions between the Controllers and the View parts. If the key parameters that determine the next page to be displayed have been already defined, the developer can use any useful methods or well-known tools, but these key parameters can remain undetermined until completion of the Web application. Therefore, this invention provides the functionality to allow developers to define and to change the parameters used in the design phase and the implementation phase as unified keys with an extraction mechanism.

Background of this invention

New Concept for Web Applications

The Web Application will use a new concept for the page flow. The Web Application consists of pages which are paired sets for an HTTP request and its HTTP response. There are key parameters linking a page and the following pages, so the developer should manually map the page flow to the key parameters that determines the next page. Designers or developers usually write a description of the page flow in the design phase and concretely define the keys between a page and the following pages in the implementation phase. Thus these phases interact a lot but these interactions are actually defined in another development phase in the old (current) development style. These definitions should be integrated as unified data in the whole application.

Iterative Development

In most Web applications, the page flow needs to be redesigned until completion of the application. First, customers want a demonstration or a prototype of the new Web application to clarify and determine the details of its functions. Second, customers and developers attempt to improve the user interface to make it a competitive application. Therefore an effective method to design the Interaction Controller is urgently needed for such iterative development.
