An impact rating says how much a table matters to the business, and sets the trust score the table should reach. A table that meets its target shows Above Target; one that misses shows Below Target.
Manage the ratings on Settings > Trust Scores > Impact Ratings. Set a table's rating from Trust Score Performance on the table's Info tab.
Default ratings
| Impact rating | Target Trust Score | Target Quality Score | Target Coverage Score |
|---|---|---|---|
| 1 - Very Low | 1 | 50 | 40 |
| 2 - Low | 2 | 80 | 50 |
| 3 - Moderate | 3 | 90 | 70 |
| 4 - High | 4 | 95 | 90 |
| 5 - Critical | 4.95 | 99 | 100 |
| 0 - Unknown | 0 | 0 | 0 |
The target trust score is on the 0 to 5 star scale. The quality and coverage targets are percentages. You can change the targets, rename the ratings, add ratings and choose which one is the Global Default for newly cataloged tables. Out of the box that is 0 - Unknown.
How the target badge is set
Each time trust scores are calculated, every table gets one of three badges:
| Badge | When |
|---|---|
| Above Target | The table had test runs in the look back period and its trust score is at or above its rating's target trust score |
| Below Target | The table had test runs in the look back period and its trust score is below the target |
| Unknown | The table had no test runs in the look back period, or its rating's target trust score is 0 or empty |
Only the target trust score decides the badge. The target quality and coverage scores are shown beside the actual scores and returned by the REST API, but a table can miss its quality target and still be Above Target.
Because every table starts as 0 - Unknown, tables have no badge until someone assigns an impact rating.
Where badges are used
- The badge appears with the trust score stars and in Catalog lists.
- Schema and data source pages count tables Above Target, Below Target and Unknown, per impact rating.
- When a table's badge changes, Validatar raises a TrustedTableBadgeUpdated event, which notifications and integrations can act on.
