摘　　要：从支持ASP服务模式的网络CAD系统的特定需求出发,分析了当前网络CAD系统的优缺点。提出支持动态数据共享的网络CAD系统的概念及系统结构,并以J2EE平台的JAX-RPC技术为基础,实现了一个支持动态数据共享的二维网络CAD原型系统。与传统的网络CAD系统相比,本系统能够支持设计数据实时更新、计算引擎集中维护以及灵活的计费方式。该系统具有良好的可扩展性。According to the requirements of supporting ASP （Application Service Provider） service, this paper analyzes the advantages/disadvantages of state-of-art internet-based CAD systems. The concept and system structure of DDS （Dynamic Data Sharing） are proposed as the key to keep the data consistence of the internet-based CAD system. Based on the JAX-RPC techniques of J2EE platform, a 2D internet-based CAD system is developed to support DDS in the design process. Compared with traditional internet-based CAD systems, the developed system supports real-time data updating, centralized computing engine maintenance and flexible charge of service fees. The system is so flexible that it can be easily extended to include more functions.
