Datafold computes column-level lineage by:
Ingesting, parsing and analyzing SQL logs from your databases and data warehouses to infer dependencies between SQL statements, including those that create, modify, and read data.
Augmenting the metadata graph with various sources, including metadata from the orchestration tools (e.g., dbt), BI tools, and user-provided documentation.
Datafold provides a searchbar to find relevant assets:
