DATA QUALITY ASSESSMENT |
| 摘要 |
According to one embodiment of the present invention, a system assesses the quality of column data. The system assigns a pre-defined domain to one or more columns of the data based on a validity condition for the domain, applies the validity condition for the domain assigned to a column to data values in the column to compute a data quality metric for the column, and computes and displays a metric for a group of columns based on the computed data quality metric of at least one column in the group. Embodiments of the present invention further include a method and computer program product for assessing the quality of column data in substantially the same manners described above. |

1. A computer-implemented method for assessing the quality of data comprising:
assigning a pre-defined domain to one or more columns of the data based on a validity condition for the domain; applying the validity condition for the domain assigned to a column to data values in the column to compute a data quality metric for the column; and computing and displaying a metric for one or more groups of columns based on the computed data quality metric of at least one column in each group. |
