Summary: High reactivity cannot be achieved without each object being replicated on every site, when assuming a nonnegligible network latency in a cooperative design document system. It is an austerity challenge for concurrency control, and causes some new problems, such as intention-violation. The author designed a concurrency control method based on marking, which accords with integrity consistency model. However, it is inefficient at judging causality and concurrent operation. This paper brings forward an improved algorithm to solve this problem.
