Hotel Booking Snowflake Schema

Hotel booking snowflake schema

This hotel booking snowflake schema records each stay in FactStay with its nights and room revenue. The fact links to check-in date, guest and room. Guest details connect to country, while room details connect through room type to property. These separate levels make it possible to report revenue by property, room type, guest country or arrival period without repeating descriptive values throughout the fact table. The model is useful for hospitality groups that maintain shared property and room-type hierarchies across locations. It also keeps local room details separate from the cross-property categories used for management reporting. This improves consistency when properties share a central reporting model across a portfolio.
