Abstract:
1. A computer-implemented method for generating metadata describing relationships among data sets comprising: at a hardware processor, receiving quantitative data comprising a plurality of columns of data; at the hardware processor, analyzing the quantitative data to determine hierarchical relationships among the columns of data based at least in part on at least one selected from the group consisting of: storing, at a storage device, metadata representing the determined hierarchical relationships; wherein each column comprises a plurality of rows, and wherein analyzing the quantitative data to determine hierarchical relationships among the columns of data comprises, for at least one pair of columns: establishing a mapping of a first column to a second column; establishing a mapping of the second column to the first column; determining the number of unique values in the first column; determining the number of unique values in the second column; for each unique value in the first column, determine a first set of different unique values in the second column; for each unique value in the second column, determine a second set of different unique values in the first column; and identifying relationships based on the determined first and second sets.
