In this lesson
pick between warehouse, lake, and lakehouse for a reporting need.
Planned topics
- Warehouse: modeled, cleaned, structured data with fast SQL; best for finance and KPI reporting.
- Lake: cheap storage of raw files of any shape; best for exploration, logs, and data science; quality is up to you.
- Lakehouse: lake storage with table features (transactions, schema) so one copy serves both; newer, so check team skills.
- Choose from the questions asked, the data shapes, and the team, not from fashion.
