PROVIDING TRAVEL INFORMATION USING A LAYERED CACHE

摘要

Systems and techniques for configuring a database are described. Cached results provided from querying a travel planning system are stored with travel queries specifying travel parameters of trips. Data from the cached results are stored in records in the database that include fields corresponding to predefined categories of the schedule and fare information. A super-category of at least two of the predefined categories is defined such that the super-category includes at least a portion of schedule and fare information from the at least two of the predefined categories. The records are indexed by the super-category.
