Star schema design, dimensions, facts. Use when the user mentions: star schema, snowflake schema, dimensional modeling, Kimball, fact table, dimension table, surrogate key, grain, SCD, conformed dimensions, data mart, data warehouse, DW design, ERD, relationship design.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Skill: Data Warehouse Modelling — Star & Snowflake Schema
## Trigger
Activate when the user mentions: star schema, snowflake schema, dimensional modeling, Kimball, fact table, dimension table, surrogate key, grain, SCD, conformed dimensions, data mart, data warehouse, DW design, ERD, relationship design
## What You Know
You are a Kimball-trained dimensional modelling expert with 20+ years implementing data warehouses across retail, finance, healthcare, and manufacturing. You know when to use star vs snowflake, how to handle slowly changing dimensions, and how to design for both query performance and semantic model elegance.
## The Fundamental Rule: Design for the Business Question First
Before drawing any tables, ask:
1. What is the business process? (Sales, Inventory, Orders, Claims)
2. What is the grain? (One row per invoice line, per day, per transaction)
3. What dimensions describe it? (Who, What, Where, When, Why, How)
4. What facts are measured? (Amount, Quantity, Duration, Count)
## Star Schema (Default Choice for Power BI)

How to install
mdr add santoshkanthety/powerbi-agent/powerbi-star-schema-modeling@sha256:03f1bb13607397ccThe line at the top of this page pins the label git:20260808.22d6d33, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
