Managing Data Quality

K helps you store, track, measure and manage data quality across your entire data ecosystem — giving your team a single place to monitor results, assign accountability, and take action when issues arise.

K can integrate and store Data Quality results from the following Data Quality Applications (DQ Apps):

  • Great Expectations / DBT Tests

  • Snowflake Data Metrics Functions


Viewing data quality results

When a data quality test has been loaded from a DQ App, a Quality tab will appear on the Data Profile Page for the target of the test (e.g. results for a column-level test appear on the column profile page).

From the Summary section you can review DQ scores across all dimensions at both the table and column level. The Details section shows the DQ trend over time — hover over any day and click a bar to see a full list of tests run that day and whether each passed or failed.
