Getting Started with dbt: Transforming Data the Modern Way

Why everyone is talking about dbt?
DBT (data build tool) is an open-source command-line tool that enables data analysts and engineers to transform data in their warehouse more effectively using SQL and software engineering best practices.
In the era of the modern data stack—driven by the explosion of cloud data warehouses like Snowflake, BigQuery, Databricks, and Azure Synapse—organizations need scalable, maintainable, and version-controlled data transformation workflows to keep up with growing data complexity and demand.
So why is everyone talking about dbt now? Because it bridges the gap between data engineering and analytics by bringing software engineering principles—like modular code, testing, and CI/CD—into the analytics workflow, making it the backbone of modern data transformation.
What is dbt?
dbt (data build tool) is a SQL-based transformation tool that empowers data analysts and engineers to turn raw data into clean, trusted datasets using software engineering best practices—like modular code, version control, testing, and documentation.
Unlike traditional ETL tools, dbt focuses exclusively on the ‘T’ in ELT—Transformation—operating under the assumption that raw data is already loaded into a cloud data warehouse or lakehouse. This design makes dbt an ideal tool for implementing structured transformation workflows, such as the Medallion Architecture (Bronze, Silver, Gold layers). In this pattern:
Bronze represents raw ingested data,
Silver includes cleaned and conformed data,
Gold provides business-ready, analytics-optimized datasets.
dbt allows you to build these layers as modular SQL models with clear dependencies, making the transformation pipeline more transparent, testable, and scalable.
dbt is available in two forms:
dbt Core – an open-source command-line tool that integrates with orchestration tools like Airflow, Azure Data Factory, or GitHub Actions.
dbt Cloud – a fully managed SaaS offering with features like a web-based IDE, job scheduling, CI/CD, and team collaboration.
Together, dbt Core and Cloud enable teams to manage transformations across medallion layers with confidence, speed, and reproducibility—core principles of the modern data stack.
Why is dbt so popular?
dbt has rapidly become the go-to tool for data transformation in modern analytics workflows. Its popularity stems from a combination of simplicity, scalability, and powerful features that align with both data engineering and analytics needs:
- SQL-first approach: dbt is built around SQL, the language most familiar to analysts. This empowers analytics teams to take ownership of transformation logic without relying heavily on data engineers, bridging the gap between analytics and engineering.
- Version control with Git: All dbt projects are just code, so they can be managed with Git—bringing collaboration, code review, change tracking, and CI/CD into the analytics workflow, just like in software engineering.
- Modularity with Jinja and macros: dbt supports Jinja templating, allowing users to write reusable, modular code using macros and variables. This makes complex transformations easier to manage and replicate across models and projects.
- Automated documentation with lineage graphs: dbt auto-generates documentation for your data models, including column-level metadata and interactive lineage graphs that visualize dependencies—helping teams understand and trust the data pipeline.
- Testing and data quality checks built-in: With built-in tests for nulls, uniqueness, relationships, and custom conditions, dbt helps catch data quality issues early in the transformation process, making pipelines more reliable.
- Deployment-friendly with dbt Cloud and CI/CD: dbt Cloud simplifies deployment with features like job scheduling, environment management, and integrations with CI/CD tools like GitHub Actions, Azure DevOps, and GitLab.
- Community-driven development: dbt has a vibrant open-source community that contributes packages, plugins, and best practices. The dbt Slack community and forums are active hubs for learning, sharing, and support.
In short, dbt brings the rigor of software engineering into the data transformation layer—without demanding complex infrastructure—making it a cornerstone of the modern data stack.
How dbt fits into the Modern Data Stack
In the modern data stack, dbt sits squarely in the transformation layer, taking over after raw data is ingested into a cloud data platform like BigQuery, Snowflake, Redshift, Azure Synapse, or Databricks.
Here’s how it fits:
- Post-ingestion transformation: Once data is loaded into your warehouse or lakehouse (via tools like Fivetran, Azure Data Factory, or custom pipelines), dbt transforms that raw data into clean, analytics-ready tables using modular SQL models—often structured in Bronze, Silver, and Gold layers.
- Seamless orchestration: dbt plays well with modern orchestration tools like Apache Airflow, Dagster, Prefect, or the built-in dbt Cloud Scheduler. These tools can schedule and monitor dbt runs as part of a larger data pipeline, ensuring transformations happen reliably and on time.
- Composable and decoupled: dbt doesn’t manage data ingestion or storage—it focuses purely on transformation. This decoupling makes it easy to integrate with other best-in-class tools in the stack and swap components as your needs evolve.
By sitting between ingestion and analytics, dbt acts as the transformation engine that cleans, tests, documents, and prepares data—making it a critical layer in building trustworthy and scalable data platforms.
What’s New and What’s Coming
dbt Labs has recently expanded its integration with Microsoft, notably by making dbt Cloud available for Microsoft Fabric. This collaboration enables data teams to perform SQL-based transformations directly within Fabric’s unified SaaS platform, streamlining workflows and enhancing data governance.

Conclusion
As data teams strive to deliver faster insights, cleaner pipelines, and more trustworthy analytics, dbt has emerged as the backbone of modern data transformation. By embracing SQL, version control, modular design, automated documentation, and testing—all grounded in software engineering best practices—dbt empowers both analysts and engineers to collaborate more effectively.
Whether you’re working in BigQuery, Snowflake, Databricks, or Microsoft Fabric, dbt helps turn raw data into meaningful, production-grade datasets. It brings clarity, structure, and governance to transformation workflows, all while staying flexible enough to integrate with the tools you already use.
In a world where data is growing exponentially and trust in analytics is more important than ever, dbt isn’t just a tool—it’s a shift in how modern data teams work.
