STUDY ON THE DATA QUALITY MANAGEMENT AND THE DATA QUALITY CONTROL--A CASE STUDY OF THE EARTH SYSTEM SCIENCE DATA SHARING PROJECT

摘要

With the rapid accumulation of scientific data, there has formed mass data storage, which is ascending in every minute. So it becomes a very desiderate problem to be solved that how to manage the mass data effectively and to control the data quality scientifically. This paper analyzes several current problems in the field of scientific data management based on the author's experience on the data quality management of the Earth System Science Data Sharing Project, such as (1) the data quality problem is still not solved, (2) the absence of data living period design in data quality management, (3) the data quality management strategy always not that clear, etc. And according to the data management regulation home &abroad, the paper talks about an elementary method combining with the data classification and the quality management and some solving measures with a case study on the Earth System Science Data Sharing Project and it's soil vector data with name of the distribution map of the national soil in a scale of 1:4,000,000(1980s). At last, the paper takes a prospect of the data management & quality control problem.
