Getting started with dataform in google cloud

okay, let's dive deep into google cloud dataform. this tutorial will walk you through setting up dataform, creating your first project, defining data transformations, and managing your data pipelines. we'll use code examples to illustrate each step.

**what is dataform?**

dataform is a serverless data transformation service on google cloud. it enables you to:

* **build and manage data pipelines:** define, test, and schedule complex data transformations in a unified environment.
* **use sql (or javascript) to define transformations:** write transformations in a declarative sql-based language (or javascript), making it easy for data analysts and engineers to collaborate.
* **version control and collaboration:** dataform integrates with git, allowing you to track changes, collaborate with others, and maintain a history of your data transformations.
* **automated testing and quality assurance:** dataform automatically tests your transformations, ensuring data quality and preventing errors.
* **dependency management:** define dependencies between tables, so transformations are executed in the correct order.
* **scheduling and orchestration:** schedule your data pipelines to run automatically at regular intervals.

**prerequisites:**

1. **google cloud account:** you need an active google cloud account with billing enabled.
2. **cloud shell (recommended):** use cloud shell in the google cloud console for easy access to command-line tools.
3. **bigquery dataset:** you need a bigquery dataset where dataform will store the transformed data.
4. **basic sql knowledge:** familiarity with sql is essential for defining data transformations.
5. **(optional) git knowledge:** basic understanding of git concepts like repositories, branches, commits, and pull requests will be helpful.

**step 1: setting up your google cloud project**
