Problem
Scenario
You're working across several operational systems and need one trusted dataset for reporting and downstream operations. The source systems overlap, definitions are inconsistent, and records can arrive more than once or out of order.
Question
What’s your approach to building a single source of truth across multiple systems?
What this tests
- Conformed data modeling across overlapping systems
- ETL design for standardization and survivorship rules
- Idempotent processing and replay safety
- Data quality controls for trusted reporting
- Orchestration of multi-source dependencies
