轻量级RIA程序框架的设计与实现

Design and Implementation of Online Multimedia Process Oriented RIA Framework

RIA(Rich Internet Application)即互联网富客户端应用程序技术。基于对Flex SDK,MVC框架以及程序开发效率方面深入研究,本文设计并实现了一个轻量级RIA程序框架。框架以FlexSDK为基础,从性能层面,功能层面以及开发效率方面实现了整体提升,为RIA程序开发人员提供了一个面向中轻量级程序开发的较为完善的框架。利用例子程序经过对比测试表明,新框架能够有效的控制内存泄漏,编译文件大小,程序初始化时间,执行效率等并在一定程度上提高了开发者的工作效率和开发灵活性。

RIA stands for rich internet application.Through deep research of Flex SDK,current MVC frameworks as well as accumulated efficiency experience of program development,this paper designs and realizes a light weighted RIA framework.Based on Flex SDK,such framework realizes integral improvement from three aspects including performance,function and development efficiency and targets on medium and light programs to help programmers develop RIA.Furthermore,the contrastive test based on a program example also shows that this new framework with modified Flex SDK can control memory leak,the size of compiled files,application ＇s initialization time,execution efficiency,etc.and improve the development efficiency as well as the flexibility.
