Top use cases

Save the prompts you reuse and regenerate diagrams every time your stack changes.

Document staging, curated, and semantic layers for onboarding

Explain how facts/dimensions roll up to metrics and dashboards

Show contract boundaries and data products per domain

Highlight performance zones and cost controls

Workflow that ships

1

List sources, staging policies, and partitioning. Include freshness targets.

2

Define curated models and semantic layer components (metrics, dimensions).

3

Ask AI to show lineage from facts/dimensions to BI with owners.

4

Export and attach to metric definitions and onboarding docs.

Prompt recipes

Copy, tweak, and save in your repo so regenerations stay consistent.

"Create a warehouse diagram with staging, marts, semantic layer, and BI. Include owners and freshness."

"Show how orders_fact and customers_dim power ARR and LTV metrics. Add quality checks."

"Generate a domain-centric warehouse view for growth, product, and finance analytics."

Quality checklist

Layers are clearly separated (staging, curated, semantic).

Facts list grain, keys, and owner; dimensions list refresh.

Semantic layer shows metric definitions and consumers.

Costs and performance hotspots are marked for review.

FAQ

Should I include physical tables or logical views?

Include logical models that stakeholders recognize. Add physical notes only where performance or governance matters.

How do I show semantic layers?

Add a lane for metrics and dimensions with links to consuming dashboards and access policies.

Can AI surface unused models?

If you feed metadata on usage, the prompt can flag unused models so you can deprecate or consolidate.
