help dbt FAQ

Is dbt an ETL or ELT tool?

dbt (data build tool) is strictly a data transformation tool, meaning it handles the "T" in an ELT (Extract, Load, Transform) process. The data must first be extracted and loaded into a data warehouse like Snowflake or BigQuery before dbt applies SQL transformations.

What language do you write dbt models in?

Data engineers write dbt models using standard SQL (Structured Query Language). dbt then compiles these SQL files and orchestrates their execution in the underlying data warehouse.

Does dbt offer a free version?

Yes, dbt offers dbt Core, which is a free and open-source command-line interface (CLI) tool. For teams that need a managed cloud environment with a visual interface, they offer paid tiered plans under dbt Cloud.

What is a dbt macro?

A macro in dbt is a piece of reusable Jinja code that allows developers to write SQL functions dynamically. Macros are heavily used to reduce repetition and keep complex data pipelines clean and maintainable.
