Unity Catalog Object Model
Three-level namespace, broadest to most specific:
Metastore → Catalog → Schema (database) → Table/View
Objects are referenced as catalog.schema.table.
Lineage
Unity Catalog automatically captures data lineage — table- and column-level — showing upstream and downstream dependencies. Use it for impact analysis before making schema changes.
