摘要
本文讨论了在数据集成过程中遇到的数据合并问题,主要包括重复记录判断(对象识别技术)和重复记录的冲突处理(冲突解决机制)等,提出了比较实用、有效的方法,并通过实验对多表合并的两种算法进行了比较,指出了需要进一步改进的方向。
This paper presentes some problems and their solutions when carrying out data integrating. The problems mainly include duplicated records identification (Object Identification Technique) and confilict processing for duplicated records (Conflict Resolution Mechanism). We propose a practical and available method and according our experiment results we compare two merging algorithms merging multiple tables into one target table.At last we pointe out some aspects that needs to improve.
