Add Endorsements, Warnings, and Deprecation Messages to Data¶
Alation makes it quick and easy to learn about the quality of data and to review it. On every saved query, filter, column, table, schema, or data source page you can Endorse, Warn, or Deprecate your data. Select the green, yellow, or red circle next to the name of your data to indicate its quality.
Have you found some great insights? Add an endorsement by clicking the green circle. Are you aware of missing data? Add a warning (yellow circle) with an explanation of the issue. In those cases where an object should be avoided altogether, add a deprecation (red circle) to help users steer clear of data quality issues; add a note and use the @ symbol to directly link to an alternative data object that will guide users to authenticated data.
When a user puts a warning or deprecation on an object, Alation sends an email to anyone that has mentioned it in a query, sharing the annotation with them as well as links to their queries that are potentially affected by it.
