摘要
操作转换方法是实时协同编辑中进行并发控制的一种常用方法。论文首先介绍了复制式协同编辑系统的一致性模型,阐述了操作转换方法的基本流程,详细分析了七种典型操作转换方法实现三个一致性条件的方案。接着分析了操作转换方法的应用扩展,最后针对面向三维协同设计的应用扩展进行讨论。
The transformation-oriented concurrency control approaches are rather popular in real-time cooperative editing system.In this paper,consistency model of real-time cooperative editing system with full-replicated architecture,followed by main flow of operational transformation were previous introduced.Then,the methods of consistency maintenance of seven typical operational transformation approaches were analyzed in detail.And application extension of operational transformation approaches was analyzed.Finally,application extension to 3D cooperative design was discussed.
