What this diagram shows
- Direct bookings and OTA bookings share one inventory
- The channel manager keeps rates and availability in sync
- Revenue management adjusts rates by demand
Prompt used
Hotel reservation system architecture: guests book on the hotel website/app through a booking engine; OTAs (Booking.com, MakeMyTrip) connect through a channel manager. The central reservation system holds rates and inventory, each hotel runs a property management system (check-in, rooms, folios), a revenue management system sets rates by demand, and a CRM/loyalty system recognises returning guests. Payments go through a gateway.
