基于属性等价的异构多数据源模式合并

Model Aggregation of Heterogeneous Multi-Data Sources Based on Attribute Equivalence

为了解决在多种数据源例如各类关系数据库、文本下实现为用户提供透明的、形式一致、概念统一的集成化数据查询 操作界面 ,在定义各类对象类属性等价并扩充到对象类等价的基础上 ,提出了一种多数据源模式合并的算法 。

To provide a transparent, uniform and conceptually consistent integrated data query/manipulate on interface under the environment of such multi data sources as various rational databases and text,a model aggregation algorithm for multi data sources is proposed based on the definition of attribute equivalence of object classes and its extension to the equivalence of object class.The proposed algorithm has been implemented in inter connection of TMN sub systems.
