It is a command line tool that enables data analysts and engineers to transform data in their warehouses more effectively.
What need does dbt fulfill?
dbt (data build tool) simplifies the workflow for transforming raw data into data models consumable for analytics.
dbt makes it easy and fast for data teams to write, test, and orchestrate data pipelines. Transformations are written as templated SQL select statements and automatically orchestrated with a CLI tool. And because one only needs SQL to start with dbt, non-engineers can adopt this superpower too.
Importantly, dbt often enables data analysts to build their own analytical assets and intuitively introduces to them good software development practices (like abstraction and testing).
