【摘要】 基于对ＣＳＣＷ中复制结构的支持结构、应用模型、操作执行次序和失序纠正等方面的分析，提出了一种适用于复制结构的ＣＳＣＷ并发控制框架模型．采用向量时间方法，在规定操作执行次序方面定义一种新的字典全序，并设计了通用失序纠正策略．此策略为达到执行操作集合结果的一致性提供了一种有效方法，为并发控制框架模型提供了一种算法基础更多还原

【Abstract】 It specified the functional requirement of designing a concurrency control scheme for CSCW including supporting architecture, application model, operation executing sequence, and re ordering of operation execution. A concurrency control framework for replicated CSCW was presented based on the above analysis. To support the framework,a new total order, the lexicographic total order, for operation execution was defined. Based on it, a general re ordering scheme was designed and it provided an effective approach to achieve the convergence of operation results.更多还原
