摘要
通过对多数据库系统 (MDBS)模式集成中不同类型完整性约束的分析 ,提出并讨论了用于处理完整性约束的若干规则 .这些规则不仅可以应用于模式集成 ,而且还可适用于模式变换、视图派生等模式重构中 .
Some rules for dealing with the integrity constraints are presented by analyzing the different types of integrity constraints in schema integration multidatabase systems. These rules are not only applied in the case of schema integration but also suitable for schema restructuring, such as schema transformation and view derivation. And the application of these rules are demonstrated by means of a practical case.
