| 摘 要： | 传统的版本管理系统只提供基于文件系统的版本管理,难以支持需要图状结构的应用的版本管理.提出一种基于有向带圈图(DCG)的版本管理系统DCG-VCS,它能够处理任意有向带圈图结构的版本化问题.在分析传统版本管理系统所存在问题的基础上,提出了有向带圈图结构DCG的版本化模型,详细阐述了DCG-VCS的主要设计问题,包括中央库的储存模型和版本编号、签入和签出算法,一致性维护和签入并发性保证等.最后讨论了DCG-VCS在语义网络的知识管理中的应用.

| Abstract: | In contrast to the traditional Version Control System(VCS) which is only based on filesystem and which doesn't support applications needing graph-structured versioning,a Directed-Cyclic-Graph(DCG)-based VCS is put forward.DCG-VCS can solve arbitrary versioning problems of DCG-structure.The problems which exist in the traditional VCS are discussed first,and then DCG-VCS versioning model and solutions,especially DCG-VCS problem spaces are explained in detail,including the storage model and revision mechanism of the central repository,the checkin and checkout algorithms,and the consistency concurrency model.And finally the application of DCG-VCS in knowledge management of symantic Web is introduced. |
