- /hotels hotel dimension table (tier, stars, review score)
- /rates full rates fact — all sources, room types, scrape history in one flat table
- /occupancy Newbook occupancy per date × room category
Rates UNION covers Booking.com scrapes, direct competitor engines (with
configured room/rate labels), and own hotel Newbook headline rates.
