摘 要: 针对支持动态建模功能分布式产品数据管理系统中数据的备份和恢复问题,研究了在模型发生改变后如何对原有数据、代码的处理使之适应于新的模型.结合支持动态建模的分布式产品数据管理系统的特点,提出了一套备份恢复方案,可以对分布式系统的数据备份恢复进行管理,并配合动态建模工具对模型改变后的数据、代码进行管理. To deal with the backup and recovery of the data in the distributed PDM system based on the dynamic modeling, the paper presents about how to make the data and source of old model suitable to the new one after model is modified. The paper provides a set of solution for backup and recovery, which combines the characteristics of the distributed PDM system and the dynamic modeling. It can manage the backup and recovery of the data in the distributed PDM system, and cooperate with the dynamic modeling tools to manage the data and source of the new model after modified.
