System Design : Airbnb | Booking.com online hotel reservation system with Search and Ranking

I have explained about the system design and architecture of Airbnb.com or Booking.com. Below is the scope of the presentation. A) Create Guest/Host Account B) Search lodging 1) How search index is updated dynamically after room is reserved. (Room should not be visible in search) 2) Ranking infrastructure for better search results (Good ranking, good conversion) C) Become a host D) Reserving/Booking rooms (Avoid two users booking the same room at same time) There is also a screen dedicated to database design for Airbnb and explained in detail. Following are the restful API's in the System design guestAccountService ( app_key, username, password, address) hostAccountService ( app_key, username, password, address) becomeHostService (app_key, location, availableFrom, availabeTo, roomDetails, description) searchService( app_key, location, checkin_date, check_out_date, guestCount) viewRoomService( app_key, room_id, checkin_date, check_out_date, guestCount) viewReviewService ( app_key, room_id); reserverService( app_key, creditcardInfo, room_id, checkin_date, check_out_date, guestCount) Also, there is an extensive talk about the search services with ranking of the search data. Finally, I demonstrated how to use AWS services to build a system for Airbnb. Understanding the ranking will also help you to build recommendation system for Hotel booking.
