摘要
在不可忽略的网络延迟的情况下 ,由于 CSCW系统的高响应度的要求 ,系统需要使用完全复制分布式结构 .这是对并发控制的严峻挑战 ,从而也产生了新的问题 ,如违背操作意愿 .基于文档标注的并发控制方法 ,引入状态向量 ,不仅符合整体一致性模型 ,而且易于理解 ,并且效率较高 .
High reactivity cannot be achieved without each object being replicated on every site, when assuming a nonnegligible network latency in a CSCW system. It is an austerity challenge for concurrency control, and can cause some new problems, such as intention violation. A new algorithm about concurrency control, based on document marking, uses state vector. It not only accords with the integrity consistency model, but also is easy to understand and more efficient.
