Your question is Schema Design for Warehouses. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain your approach to schema design for a data warehouse supporting cross-functional operations.
Discuss how you would identify business processes, define fact table grain, choose dimensional or normalized structures, and create conformed dimensions for shared reporting. Address slowly changing dimensions, surrogate keys, source-to-target mappings, data quality checks, lineage, access controls, incremental loading, and how the schema would support both operational dashboards and ad hoc analysis.
