Dataform Core

Dataform Core is an open source meta-language to create SQL tables and workflows in BigQuery. Dataform Core extends SQL by providing a dependency management system, automated data quality testing, and data documentation.

Using Dataform Core, data teams can build scalable SQL data transformation pipelines following software engineering best practices, like version control and testing.

For more details, see how Dataform works.
