Data Transformation with dbt

You’ll learn how to transform data using dbt (data build tool), covering:

• dbt Fundamentals: Understand what dbt is and how it brings software engineering practices to data transformation
• Project Setup: Learn how to initialize a dbt project, configure your warehouse connection, and structure your models
• Models and Materialization: Create your first dbt models and understand different materialization strategies (view, table, incremental)
• Testing and Documentation: Implement data quality tests and auto-generate documentation for your data models
• Jinja Templating: Use Jinja for dynamic SQL generation, making your transformations more maintainable and reusable
• References and Dependencies: Learn how to reference other models and manage model dependencies
• Sources and Seeds: Configure source data connections and manage static reference data
• Macros and Packages: Create reusable macros and leverage community packages to extend functionality
• Incremental Models: Optimize performance by only processing new or changed data
• Deployment and Orchestration: Set up dbt Cloud or integrate with Airflow for production deployment

Here’s a minimal dbt model example, models/staging/stg_customers.sql:

with source as (
    select * from {{ source('raw', 'customers') }}
),

renamed as (
    select
        id as customer_id,
        first_name,
        last_name,
        email,
        created_at
    from source
)

select * from renamedCopy to clipboardErrorCopied
