摘要

提出了一种支持本地数据库语义(如完整性约束)向全局级传播的四层体系结构。这种传播可以派生出任何一个本地组件都无法识别的新约束，并有可能显著降低异构数据库系统中的查询处理成本。

Towards an active schema integration architecture for heterogeneous database systems

A four-layered architecture is proposed for supporting the propagation of local database semantics (e.g., integrity constraints) to the global level. This propagation enables the derivation of new constraints that could not have been recognized by any one of the local components, and offers the potential for significantly reducing query processing costs in heterogeneous database systems.<>
