Design And Implementation Of RIA-Oriented MVC Framework

RIA(Rich Internet Application) is a new generation of web applications, which integrates best UI functions of desktop applications and the popularity and fast,low cost of deployment of web applications and the interactivity of real-time multimedia.Based on reuse technology and design methods of software frameworks and service-oriented idea, the RIA domain requirement is analyzed and RIADF (Rich Internet Application Distribution Framework) is put forward. RIADF defines the basic design goals and basic functions modules of client/server in RIA, as well as a combined model of instance-based and service-based interactions between clients and servers. RIADF also defines three types of services: application definition request service, businesss logic request service and web data service. RIADF gives out basic theory guidelines for RIA development.Web frameworks based on MVC design model have great reusability. Based on RIADF, a new framework RIADF/MVC is put forward to ease RIA development, combined with web service, design patterns, component interaction technologies. The greatest feature of this framework is that it focuses on the client-side view, and uses XMLRPC protocol as basic interaction protocol, and the framework has implemented fine-grained manipulating of client view components. A prototype system of RIADF/MVC has been designed based on ASP.NET, and the details of design and implementation of the framework including some important components have also been outlined. A real project demonstrates the basic development diagram based on this framework and it also verfies the reusability of the framework and basic support of software resue.
