Claim:
1. A computer-implemented method for assessing the quality of data comprising: applying a set of validity conditions for each of a plurality of pre-defined domains to each of a plurality of columns of the data, wherein at least one pre-defined domain is associated with a plurality of rules specifying the set of validity conditions for data of that at least one pre-defined domain; assigning pre-defined domains selected from among the plurality of pre-defined domains to corresponding columns of the data based on satisfaction of the set of validity conditions for the pre-defined domains, wherein each of at least two of the columns of the data remains unassigned to a corresponding domain; generating a group of two or more of the unassigned columns based on characteristics of the unassigned columns; creating a new domain for the group of unassigned columns with a corresponding set of validity conditions and assigning the columns of the group to the new domain; applying the set of validity conditions for the domain assigned to a column to data values in the column to compute a data quality metric for the column; and displaying a metric for one or more sets of columns that is computed based on the computed data quality metric of at least one column in each set of columns.
