具有数据清理功能的交互式数据迁移及应用

针对众多论文对数据迁移的研究多是泛泛地介绍数据迁移的方法,而没有考虑数据迁移过程中的数据清理问题,提出了一种具有数据清理功能的交互式数据迁移技术.该技术把数据迁移和数据清理紧密地结合在一起,具有开放的规则库和算法库.通过在规则库中定义规则以及从算法库中选择合适的清理算法,不仅能灵活、准确地完成数据的迁移,还能保证数据迁移后新系统的数据质量.该技术被应用于医疗保险信息系统再工程项目,取得很好的效果,从而说明这种数据迁移技术在实践中是可行的.

Interactive data migration with data cleaning function and its application

The ways of data migration are studied in many articles, but the data cleaning is not considered in the process of data migration.An interactive data migration technology with data cleaning function is proposed. This data migration technique combines data migration and data cleaning together tightly, and has exoteric rules library and algorithms library. Through defining rules in rules library and choosing proper cleaning algorithms from algorithms library, this data migration method migrates the data from original system to new system and ensures data quality. This technique is used in data migration of a medical insurance information system and the result is very good.This declarative data migration technique is feasible in practice.
