Data Build Tool (dbt) integration

IBM® watsonx.data integrates with Data Build Tool (dbt), which is a data analytics tool that helps to transform the data in watsonx.data to simpler and accessible form for business users. It allows analysts and scientists to build data pipelines by using different models and have curated data for decision making. You can run SQL queries by using the db tool and analyse data available in watsonx.data.

dbt allows analysts and scientists with some of the following data related tasks:

Manage complex work flows for data transformation and support features like version control, modular code, and continuous integration.
Prepare data for reporting and analysis by transforming raw data into a structured format, making it easier to create insights.
Create layered, reusable models that represent different stages of data transformation.
Ensure reliability of the transformations by identifying issues in the process.
Generate clear and easy-to-understand documentation for the models and provide visualization of data lineage to track how data moves through the pipeline.
Handle dependencies between models and ensure the transformations run in the correct sequence and can integrate with larger data workflow.

dbt is supported in watsonx.data for Spark and Presto engines. dbt uses the following data build tool (dbt) adapters to connect dbt core with Spark and Presto engines. The adapters helps to build, test, and document data models.

dbt-watsonx-presto to connect to Presto
dbt-watsonx-spark to connect to Apache Spark
