  • Data quality assessment
    Patent number: 9594797
    Abstract: 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.
    Type: Grant
