Key takeaways
- A typical Data Architect day mixes focused individual work (define conceptual, logical and physical models plus the grain of every core fact table) with collaboration and reviews.
- The skills you'll use daily: Dimensional modelling, Data Vault, Snowflake / BigQuery / Databricks, SQL, Data governance.
- Day-to-day, Data Architects spend most time on: define conceptual, logical and physical models plus the grain of every core fact table; choose warehouse, lakehouse or hybrid storage patterns and the table formats behind them; establish a business glossary so each metric carries one agreed definition.

What separates a data architect from a data engineer?
