摘要: 映射表是对等数据管理系统广泛使用的一种数据映射工具。通过构造大量新的映射关系,映射推导技术能极大地提高数据共享程度。已有的映射推导研究集中于理论分析,该文在探讨映射推导问题的基础上,从用户角度出发设计了一个映射关系模型,在此基础上,给出了数据映射推导系统的总体框架。

Abstract: Mapping table is a popular tool of data mappings in peer data management systems. Mapping inference technique creates a large number of new mappings, which facilities the data share in systems. The existing research in this area concentrates on theory analysis. According to the study of inference problems of data mappings, a mapping relation model is proposed and the architecture of a data mapping inference system is given.

Key words: Peer data management system, Mapping table, Data mapping, Mapping inference
