| 摘 要： | 应用共享技术是计算机支持的协同工作（CSCW）系统中关键技术之一.首先分别给出了集中式、复制式和混合式3种共享机制的定义和结构图,并且分别分析了这3种共享机制的优缺点.在分析和比较了传统的应用共享技术的基础之上,提出了基于悲观式和乐观式并发访问控制策略下的应用共享机制,并对混合式应用共享进行了深入的分析.最后给出了一个基于乐观式应用共享模式的协同CAD设计具体实例.

| Abstract: | Application sharing is one of key technology for computer supported cooperative work(CSCW).Firstly,the definitions and structural charts for the three kinds of sharing mechanisms are given respectively including centralized application sharing,ectypal ap-plication sharing and mixed application sharing.The advantages and disadvantages of the three kinds of sharing mechanisms are analyzed.Based on analysis and comparison on traditional application sharing,application sharing mechanisms are put forward for concurrent con-trol tactic of pessimism and optimism,and mixed application sharing is analyzed in-depth.Ultimately a example for cooperative CAD design is put forward based on the model of optimism application sharing. |
