DQ Discovery

DQ Discovery is the user-facing browse layer for the Data Quality Portal. Three pages live under it: Catalog Browser, DQ Reports, and Team Ownership.

Catalog Browser (/data-quality/catalog-browser)​

A UC tree with quality overlays. Each table row shows:

  • Table name + FQN
  • Trust score badge (Trust Scores)
  • Certification status badge (Certifications)
  • Active anomaly count
  • Last DQ run timestamp
  • Owner team

Filters narrow by domain, score band, certification status, owner.

Use this page when you want "show me every certified table in the Sales domain with score < 80".

DQ Reports (/data-quality/reports)​

Pre-built reports for common DQ questions. Each report runs on demand or via Scheduling:

ReportWhat it shows

Team Ownership (/data-quality/ownership)​

Maps tables to owner teams and surfaces:

  • Tables per team — count + scope
  • Score per team — rollup of owned tables
  • Coverage per team — % of owned tables with rules
  • Open incidents per team

Click a team to see its tables and quality dashboard.

Bulk reassignment is possible via the Reassign button on a multi-select — useful when a team splits or owners change.
