Core Concepts
These pages define the vocabulary used across tablespec. They are written for technical readers who understand tables and pipelines but may be new to UMF, ingested bronze, Great Expectations, dbt, or Databricks Lakeflow.
Defines the data-layer boundary: raw records for audit, ingested bronze for source-table contracts, and silver for business decisions.
Defines the UMF source-table spec: columns, types, per-context nullability, sources, relationships, and expectations.
Defines the reusable catalog of generated files: SQL DDL, ingest SQL, PySpark and JSON schemas, Great Expectations suites, dbt projects, and Lakeflow pipelines.
Defines how generated Great Expectations suites run against raw records and typed ingested tables, including Databricks serverless behavior.
