This book shows how dbt is used to build data transformation pipelines that enable dependency management and allow for version control and automated testing. It explains how dbt is revolutionizing data transformation and the advantages that a command-line tool like dbt provides over and above the use of database stored procedures and other ETL and ELT tools that handle data transformations. At its simplest definition, dbt (or data build tool) is an open source data transformation tool commonly used for modeling data in data warehouses. It enables data professionals comfortable writing SQL to transform data in their warehouses more effectively. At a more granular level, it is a tool that has a development framework that combines modular SQL with software engineering best practices to create a better, faster, and more reliable data transformation experience. Modular SQL refers to the practice of breaking down SQL code into smaller, reusable chunks so that it can be more easily maintained, tested, and reused. Other best practices that dbt lends itself well to include version control, documentation, DevOps, and so on. For current and aspiring data professionals, including architects, developers, analysts, engineers, data scientists, and consultants who are beginning the journey of using dbt as part of their data pipeline’s transformation layer.
