Which warehouse model fits your environment?
8 questions — source system count, schema volatility, primary use case, latency needs, Data Vault experience, regulatory strictness, data volume, and timeline. Get a personalized recommendation: star, snowflake, Data Vault, or a hybrid medallion architecture.
How this works
A recommendation, not a lecture on modeling theory
Most teams pick a warehouse model by copying whatever the last consultant used, or whatever a blog post argued for. We take eight inputs that actually drive the decision — source count, schema volatility, use case, latency, Data Vault experience, compliance, volume, and timeline — and score four models against your specific answers.
You get a clear winner, the risks to watch, and the first three concrete steps to start building it.
The models
What we score you against
Star Schema
Simple, fast, built for BI. Best when sources are stable and dashboard speed is the priority.
Snowflake Schema
Normalized, disciplined, hierarchy-safe. Best when hierarchies are complex and volatile.
Data Vault 2.0
Enterprise-grade, audit-ready, schema-drift resilient. Best under heavy compliance and change.
Hybrid Medallion
Data Vault backend, star schema frontend. Best when you need both resilience and speed.
