摘要
The present invention provides a data quality measurement method based on a quartile graph, the method comprising: defining a data grid (Gx) and fitting a plurality of trend lines; scanning a data source and storing, and according to actual trends of the data, selecting a trend line and displaying data; generating data quality rules according to the determined trend line type and parameters; selecting appropriate data quality rules and measuring data quality according to a threshold. By means of defining a data grid (Gx) to store data, using a quartile graph to display data, and generating data quality rules according to the determined trend line type and parameters, and further setting a threshold according to said rules and measuring data quality, the present invention performs, for enormous amounts of data, applications such as display of data, analysis of abnormal data, and data error correction. In addition, another embodiments of the present invention provides a data quality measurement system based on a quartile graph.
