摘要
源模型和目标模型描述之间的异构性是实现模型映射的主要困难.在对模型结构特征进行抽象分析的基础上,利用树形结构对模型进行描述,通过相似度计算来找到模型间的映射关系,提出了一种基于结构的模型映射方法.该方法能够很好的实现异构数据模型之间的数据集成,不仅可为模型转换的具体实现提供理论指导,还为验证模型之间映射关系的正确性提供了依据.
The size of the gap between source model and target model has a profound impact on the efforts to create mapping rules.A model mapping approach based on structure is proposed on the basis of abstractly analyzing the characteristic of the structure of models,using a tree structure to describe the model and through calculate the similarity to find the mapping relations of models.This approach can make data integration between heterogeneous data model come true beyond compare,it can not only to be a theoretical guidance for model transformation,but also can be a measurement for validating the mapping rules between models.
