摘　　要：论文重点研究异构数据模型间的映射关系,并参考ETL框架思想,设计了针对异构数据模型间数据映射、转换和加载于一身的双向映射策略,分析并定义了数据模型间的映射关系与映射规则。基于元数据驱动理论方法设计了数据映射元模型,并将映射关系按照复杂程度分类,分为简单映射与复合映射关系,明确给出了分类原则。论文还对双向映射关系进行了描述,并分析了双向映射中遇到的问题。This paper focuses on the research of the mapping between heterogeneous data models.And using ETL framework as references,a bidirectional mapping strategy is designed combining heterogeneous data model data mapping,conversion and loading.The mapping relations and mapping rules among the data models are analyzed and defined.Based on the metadata driven theory method,the data mapping element model is designed,and the mapping relations are classified to simple mapping and compound mapping according to the different complexities,with clearly giving the classification principle.This article also describes the bidirectional mapping relations,and analyzes the problems occurring in the bidirectional mapping.
