Explain the difference between a Data Warehouse and a Data Lakehouse.

Explain the difference between a Data Warehouse and a Data Lakehouse.

Approach: Compare traditional warehouses with the hybrid lake-warehouse model.

A Data Warehouse is for structured data with strong ACID properties. A Data Lakehouse combines the cost-efficiency of a data lake with the performance and transactions of a data warehouse.

Follow-up: What technology enables Lakehouses (e.g., Iceberg, Delta)?

Key concepts: delta lake, acid on lake, unified storage.
