使用扩展GRR作为全局视图的全局事务构造

BUILDING GLOBAL TRANSACTION BASED ON THE AUGMENTED GLOBAL REFERENCE RELATION

全局视图构造与全局事务生成是数据库互操作的重要方面．已提出的若干全局视图结构在实际系统中并不足以刻划数据库结构的语义方面并正确生成全局事务．本文讨论我们对全局访问关系ＧＲＲ的扩展，并给出基于此全局视图的全局事务生成算法．

This paper discusses the global reference relation augmented with the “attribute semantic declaration” and the “equivalent attributes” as the global view of a distributed autonomous databases system, and gives the correspondent algorithm of building global transaction based on this global view structure.
