摘　　要：数据清洗可以提高数据质量。介绍了数据清洗规则库设计方法,该方法基于编程语言的反射技术和Python脚本技术实现数据清洗,可以方便、灵活且高效地解决数据清洗中错误数据的问题,具有扩展性强、易于实现和开发成本低等特点。The data quality can be improved by data cleaning. The method for designing the sim- ple rule base with data cleaning is introduced. The reflection technology based on the program- ming language and the Python scripts technology are used to realize the data cleaning. By using these technologies, the problems of erroneous data in the data cleaning process can be solved. The method has features of strong expansibility, easy realization and low development cost.
