摘要/Abstract

摘要： 介绍了数据依赖理论及如何基于数据依赖修复不一致数据，提高数据质量。首先介绍了数据依赖理论;给出了数据修复的语义假设及对应的修复操作;总结了基于数据依赖修复不一致数据的方法;最后讨论了基于数据依赖修复不一致数据的未来发展方向。

关键词: 数据依赖，不一致数据，修复，数据清洗，数据质量

Abstract: The theory of data dependencies was introduced and its application for repairing inconsistent data was discussed. Firstly, dependencies were analysized and the semantics for repairing inconsistent data were introduced. Secondly,the methods for repairing inconsistent data were analyzed. Finally, the future research topics related to repairing inconsistent data were also discussed.

Key words: Data dependency, Inconsistent data, Repair, Data cleaning, Data quality
