US Patent 10019675 Actuals cache for revenue management system analytics engine

At a data ingestion time, a travel sessionizer captures raw event data representing a plurality of bookings made by a plurality of users for a given day, identifies a plurality of cache entries corresponding to a travel property for the given day, wherein at least one of the plurality of bookings from the raw event data is for the travel property, and updates the plurality of cache entries corresponding to the travel property for the given data to reflect the at least one booking from the raw event data. At a runtime, the travel sessionizer receives a travel analytic query corresponding to the travel property, accesses at least one of the plurality of cache entries corresponding to the travel property for the given day, and executes the travel analytic query using travel data from the at least one of the plurality of cache entries.
