| 摘 要： | 局部数据库中的数据与集成数据库中的数据一致性问题一直是采用物理集成策略的多数据库系统的关键问题。本文针对ＣＩＭ环境特点,一种基于松散一致性模型的主副本异步更新机制一公告机制,来解决这一问题,本文详细这了公告机制、公告系统的设计与实现,并给出了公告处理算法,该公告机制已在甸开发的ＣＩＭＳ信息集成平台的原形系统ＳｕｐｅｒＢａｓｅ中得以实现。

| Abstract: | Data consistency problem between local data in local database and global data in integrated database is critical problem in multiple database integrated system which adopted physical integrated policy. For the features of CIMS environments, we presented a primary copy based asynchronous modification mechanism(i.e. bulletin echanism) to solve this problem. This paper discussed the design and implementation of bulletin mechanism and system in detail and gave corresponding bulletin processing algorithm. This bulletin mechanism hod been was implemented in SuperBase system. |
