摘要
为解决可移动系统在移动环境中不能进行产品数据实时更新所带来的产品数据一致性问题,提出了一种新的基于日志的产品数据乐观复制方法,采用分布式数据存储机制,定义了数据和日志的记录方式。该方法可以使用相对较小的通讯和存储开销,更有效地支持移动环境下可移动系统中数据更新和产品数据一致性控制问题。通过在某大型注塑机企业“HTMC产品数据管理系统”中的应用,证明了该方法的实用性和有效性。
To solve the consistency problem of product data in mobile system which could not be updated in real time in mobile environment under the mass customization mode. a new product data optimistic replication method based on log was presented. Distributed data storage mechanism was adopted, and the recording methods of log and data were defined. The method could support data update and data consistency control more efficiently with lower communication and storage cost in mobile environment. The method was applied in the HTMC product data management system and proved to be feasible and effective.
