摘要
通过对航空物探数据特点的研究,在航空物探数据库系统建设中设计了数据检查规则和检查流程控制方法,通过这种方式来控制数据质量,做到数据不缺失、不冗余,保证数据的正确性、唯一性和完整性。
Data constitute the foundation of a system. Correct data can give true information, whereas wrong data can misdirect the customer, resulting in heavy losses. When a system is built, we must first guarantee the correctness of the data. This paper deals with the means for data quality inspection in the aerogeophysical database system. Based on analyzing data characteristics and system requirement, the authors designed a different check means. With this means, the data are neither redundant nor insufficient, and thus the data integrity and validity can be ensured.
