When to Use dbt: Key Uses and Benefits Explained

dbt is used when you want to transform raw data inside your data warehouse with clear, version-controlled SQL models. It is ideal for automating data transformations, testing data quality, and documenting your data pipeline.

How It Works

Think of dbt as a smart assistant that helps you organize and clean your data inside your data warehouse. Instead of moving data around, it lets you write simple SQL queries to transform raw data into clean, ready-to-use tables.

It works by running these SQL queries in a specific order, like following a recipe step-by-step. This ensures your data is always accurate and up-to-date. Plus, it keeps track of changes so you can easily see what was done and fix problems quickly.

Example

This example shows a simple dbt model that selects customers with orders over $1000.

sql

with orders_over_1000 as (
    select
        customer_id,
        sum(order_amount) as total_spent
    from raw.orders
    group by customer_id
    having sum(order_amount) > 1000
)

select
    customer_id,
    total_spent
from orders_over_1000

Output

customer_id | total_spent
------------|------------
123         | 1500
456         | 2000
