Intro

Dataform core is an open source meta-language to create SQL tables and workflows. 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.

Dependency tree in a Dataform project

Note: we have recently undergone a documentation transition from docs.dataform.co to cloud.google.com/dataform/docs. Content hosted on the old document site is published from the main_v1 branch.

Get started

With the CLI

You can install the Dataform CLI tool using the following command line. Follow the docs to get started.

npm i -g @dataform/cli

In Google Cloud Platform

Dataform in Google Cloud Platform provides a fully managed experience to build scalable data transformations pipelines in BigQuery using SQL. It includes:

• a cloud development environment to develop data assets with SQL and Dataform core and version control code with GitHub, GitLab, and other Git providers.
• a fully managed, serverless orchestration environment for data pipelines, fully integrated in Google Cloud Platform.
