NocoDB setup, integration, and operations for database UI and administration. Use when setting up NocoDB locally with Docker, connecting NocoDB to external databases (Supabase, PostgreSQL), creating views and relationships, configuring security (RLS bypass, image scanning), managing backups, or troubleshooting NocoDB connectivity issues. Includes two-database architecture patterns (metadata DB vs external data source), NC_DB connection string configuration, view creation via UI, relationship auto-detection via FK constraints, and operational procedures (backup, monitoring, error handling).
