| 摘 要： | 协同图形编辑系统使得地域分散的一个设计群体借助计算机及其网络,通过协调与协作来共同完成一项任务。在协同图形编辑系统中,并发控制是实现设计者之间自然、高效地协同工作的关键技术。本文针对面向图形对象的协同图形编辑系统,设计了一种在混合式系统结构下的基于协同服务器的并发控制策略,有效地维护了各站点副本的一致性,很好地解决了针对图形设计的并发控制问题。

| Abstract: | Collaborative graphic editing Systems (CGES) allow users,spread across different locations,to work together by computer and network. Concurrency control is one of the key technologies in such systems, it ensures the designers work naturally and efficiency. In this paper, we design a Co-Server-Based Concurrency control strategy which has effectively maintained the copy of the site with good consistency for graphical object in a hybrid system structure and it gives a good solution for graphic design concurren... |
