基于双向链表的产品协同设计版本存储模型

Version Storage Model of Product Collaborative Design Based on Doubly Linked List

针对产品协同设计的版本管理的版本存储问题进行研究.在分析了目前已有的版本增量存储和完整存储技术的基础上,提出了一种将完整存储和逆增量存储相结合的产品协同设计版本存储模型.将版本的存储结构按照其父子关系定义为一个双向版本链表,当设计过程产生新的版本时,采用反复迭代和插入的方式,将其存放在版本链表结构中,以实现协同设计版本的快速存储、节约存储空间和提高版本存储的安全性.

The study is on version storages issues of the version management in the product collaborative design. Based on the analysis of the current version incremental storage and complete storage technologies, this study poses a new version storage model of product collaborative design which will combine inverse incremental storage with complete storage. The storage structure of version is defined as a two-way version of the list according to their parent-child relationship, when the design process produces a new version, it will be stored in the list structure of version by the way of repeated iteration and insertion, in order to achieve the fast storage, save the storage space and improve the security of the version storage in the product collaborative design process.
