Your question is Batch and Real-Time Hotel Data System. 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).
Design a system that stores data about hotels and supports querying in both batch and real time; which technologies/database, how to deploy it, and how users interact with it.
Asked in the System design stage. Explain the architecture, storage choices, deployment model, query paths, data ingestion, and operational safeguards. Call out assumptions where scale, freshness, availability, or query patterns are unspecified.
