浅析Cairngorm框架在基于RIA网络GIS中的应用

本文在对基于RIA网络GIS介绍的基础上,分析了该模型开发中的瓶颈问题,并针对瓶颈问题,引入了Cairngorm框架模型,设计出基于Cairngorm框架的RIA网络GIS的通用模型;同时笔者在试验反馈中,进一步改进了Cairngorm框架,提出了改进版的基于Cairngorm框架的RIA网络GIS模型。试验表明,一方面,该框架结合J2EE或.Net等技术,从很大程度上快速、安全地实现了网络GIS海量数据的通讯,另一方面,也促进了RIA网络GIS团队的协作开发,大大提高了RIA应用程序的开发效率。

Application of Cairngorm in WebGIS based on RIA

Based on the recommendation of RIA WebGIS,the author analyzed the problems of this model in practice and introduced Cairngorm frames and designed RIA WebGIS'common model based on Cairngorm;the author also mended Cairngorm and put up an improved RIA WebGIS model based on Cairngorm.The experiment showed that,on the one hand,this improved model,combining with technology such as J2EE or.Net,realized quick and safe communication of WebGIS data,on the other hand,it promoted team's collaboration of RIA WebGIS,which would make a progress in efficiency.
