DataVault4dbt - A Comprehensive Guide

4. DETAILED EXAMPLES GENERAL OVERVIEW

The DataVault4dbt package provides a comprehensive set of macros for staging and creating all the Data Vault entities necessary to build a robust Data Vault 2.0 solution. By leveraging these macros, users can automate the creation of hubs, links, satellites, and other essential components of a Data Vault model without writing SQL manually. This approach ensures consistency, scalability, and adherence to Data Vault 2.0 standards.

The typical structure of models created with DataVault4dbt includes three main parts:

1. Metadata Definition: A YAML-formatted section where metadata for the Data Vault entities is defined. This includes for example the definition of hash keys, business keys, and source models

2. Parsing of the metadata into a dictionary

3. Macro Invocation: The defined metadata are passed as parameters to the DataVault4dbt macros, which then generate the necessary SQL code based on the provided metadata
