Description

Scope

Merge PR #4, which introduces:

  • go_stores.csv

A complete stores pipeline:

  • models/01_raw/t_raw_stores.sql
  • models/02_stg/t_stg_stores.sql
  • models/03_det/t_dim_stores.sql (SCD2)

Run the pipeline:

dbt run -s +t_dim_stores

Working blueprint for building SCD2 dimensions in dbt (DuckDB): hash-based change detection, versioning, current row flag, and prior_dim_store_sk.

Use this to build t_dim_products as a scd2 table.

Test SCD2 functionality

Manually update dimension attributes in dbeaver example:

update dev.stg.t_stg_stores
set manager_name = 'Erik ten Hag'
where store_code = 'GO002'

In dbt re-run only dimension:

dbt run -s t_dim_stores

Contributor guide

Research direction
Examine the existing stores SCD2 model and adapt it for the products dimension, ensuring hash based change detection and versioning.
