Project description
Data Vault 2.0 scaffolding tool
:warning: Pre-alpha version disclaimer Please note that this package is in a pre-alpha version which means it is used internally in a small circle of users and backwards-incompatible changes might be introduced in future releases.
This tool is designed to streamline the process of creating Data Vault 2.0 entities, such as hubs, links, and satellites.
As well as building information layer objects such as dim and fact tables from a multidimensional paradigm.
How it works
User: provides a staging view stg.[entity_name] (or a table if the staging layer persisted)
with all requirements for the [entity_name] defined in the schema (how to define see below).
Tool:
- Validates metadata of the provided staging view or table.
- Generates the necessary DDL statements to create the Data Vault 2.0 entities.
- Generates ELT procedures to load data to the generated entities.
- Generates support procedures such as
meta.Drop_all_related_to_[entity_name]andelt.Run_all_related_to_[entity_name]
