Quality scores for a column

Quality metrics such as Accuracy and FIll Rate can be measured per column and aggregated for the entire dataset. The Dashboard page provides an option to view available metrics for each column in the dataset. The bottom portion of the Dashboard shows available columns per page in a dataset. Users can navigate to a different dataset and different pages within the dataset by using the filters in the Dashboard page.

Columns are grouped into the following types:

  • Indexed columns - these are columns that are flagged so that the underlying data is stored in such a way that we can manipulate potentially millions of rows of underlying data on-the-fly
  • Columns with validation rule - these are columns where we have specified the validation rule in order to measure Accuracy. Accuracy is only available for these columns
  • All columns - these are all columns in a dataset page
