Data Lineage

This project is built on a tested, documented dbt pipeline. The full dbt documentation site lets you click through the lineage graph from the raw seed all the way to the Evidence pages, and inspect every model, column, test, and exposure.

What you'll find there:

• Lineage graph — the DAG from raw_hr_dataset (seed) → staging → intermediate → marts → the five Evidence pages (modelled as dbt exposures).
• Models & columns — descriptions and data types for every model.
• Tests — the 40+ data tests (not-null/unique/relationships, range checks, and custom business-rule tests) guarding each layer.
