What are Tiers

Tiering is an important concept of data classification in Collate. Tiers should be based on the importance of data. Using Tiers, data producers or owners can define the importance of data to an organization. In Collate, Tiers are System Classification tags and can be accessed from Govern > Classification > Tier. Classification Tags: Tiers In case of tiering, it is easiest to start with the most important (Tier 1) and the least important (Tier 5) data. Once the Tier 1 or most important data is identified, organizations can focus on improving the descriptions and data quality. The Data Insights in Collate helps identify the unused datasets as Tier 5. The Tier 5 datasets can be deleted periodically to declutter. Other tiers can be added as per your organizational needs. Tags can be added to further mark the data assets.
