Orchestrate BigQuery Workloads with Dataform

(1 day)

 

Dataform is a service for data analysts to develop, test, version control, and schedule complex SQL workflows for data transformation in BigQuery. In this course, you will explore the components of Dataform core, learn how to define tables and dependencies in SQLX, document BigQuery tables and views, understand BigQuery security settings and how to manage these with Dataform, write assertions, execute SQL workflows, and explore additional advanced use cases.

Course Objectives

  • Understand the components of Dataform core.
  • Create tables and views in BigQuery using Dataform.
  • Document BigQuery tables and views.
  • Understand BigQuery security settings using Dataform.
  • Use assertions to validate data in Dataform workflows.
  • Execute Dataform SQL workflows in an automated fashion.

Audience

  • Any data analyst, data engineer, or other data professional who wishes to use Dataform to orchestrate data workloads in BigQuery.

Prerequisites

Knowledge of SQL data analysis and BigQuery as discussed in BigQuery for Data Analysis.
