摘要： A method, a search platform, a system and a storage medium for handling queries in a database system are disclosed. The database system includes at least one client and at least one search platform. The search platform maintains pre-collected search results which are associated which confidence factors. A confidence factor indicates a probability of the associated pre-collected search result being valid. The search platform receives a query indicating at least one search criterion to the search platform. The confidence factors associated with the identified pre-collected search results are utilized to increase the mean probability of pre-collected search results returned to the client of being valid. For example, pre-collected search results complying with the at least one search criterion and being associated with confidence factors having values exceeding a given threshold are returned to the client.

摘要： Pre-computed search results are re-computed within a given time interval by a computation platform. The number of pre-computed search results re-computed by the computation platform is limited by the computation platform's computation resources available for the re-computation within the given time interval. The computation resources to re-compute a pre-computed search result i depend on whether or not other pre-computed search results related to the pre-computed search result i are re-computed during the given time interval. A re-computation controller dynamically estimates the computation resources needed to re-compute pre-computed search result i depending on which other pre-computed search results related to the pre-computed search result i are selected for re-computation during the given time interval.

摘要： Pre-computed search results are re-computed to provide long-term accuracy. A re-computation controller assigns a re-computation indicator to any of the pre-computed search results. The re-computation indicator for a pre-computed search result is based on at least on a probability that the pre-computed search result is still valid, and on a re-computation frequency of the search result. Within a given time interval, a computation platform recomputes these pre-computed search results having a re-computation indicator indicating the highest need for re-computation. The number of pre-computed search results re-computed by the computation platform is limited by the computation platform's computation resources available for the re-computation within the given time interval.

摘要： A data cache platform maintains pre-computed database query results computed by a computation platform based on data maintained in the computation platform and is configured to determine probabilities of the cached database query results being outdated, to automatically issue re-computation orders to the computation platform for updating cached database query results on the basis of the determined probabilities of the pre-computed database query results being outdated and to receive the updated pre-computed database query results as results of the re-computation orders. The probability determination depends on a probabilistic model and on the occurrence of asynchronous real-time events. The real-time events are indeterministic with regard to the expiration of the cached database query results and only have a probabilistic influence on the discrepancies between the cached database query results maintained in the data cache platform and presumed actual database query results.

摘要： The method according to a preferred embodiment of the present invention provides a pre-shopping reservation tool which allows storing entire catalogues of air travels from many providers, while ensuring a high cache accuracy at limited operational costs. The system makes use of the fares knowledge to merge identical travel recommendations coming from different travel providers (airline, travel agencies) when possible, i.e. when fares are public and not negotiated for a specific travel provider. This prevents redundant prices to be stored in the system and improves its cost effectiveness. The system according to a preferred embodiment of the present invention relies on several dedicated data analysis engines to optimize the cost of data pre-computations while at the same time maintaining good data accuracy.

摘要： Handling data requests directed to a database environment including a first platform, a second platform and a control unit. The control unit receives a request, determines a prepared result corresponding to the data request and compares an update indicator of the determined prepared result with a threshold value. In response to the comparison, the control unit either retrieves the prepared result from the second platform and returns it or retrieves an updated version of the at least one prepared result from the first platform, updates the prepared result in the second platform and the associated update indicator, and returns the updated version of the prepared result. The update indicator is defined by (1 - acc) · t, wherein acc is a probability that the associated prepared result is valid and t as an age of the associated prepared result.

摘要： Pre-computed search results stored in a search platform are subdivided into a plurality of shares of related pre-computed search results including a first share D. A re-computation controller controls re-computation of the pre-computed search results on the basis of validity probabilities. The re-computation controller determines a validity trend λ i indicating a change rate of the validity probability of a pre-computed search result i over time and an instantaneous validity rate λ̂ i for the pre-computed search result i. In response to determining a difference between the instantaneous validity rate λ̂ i and the validity trend λ i exceeding a given extent, the re-computation controller adjusts the validity probabilities being associated with other pre-computed search results included in a second share D' being correlated to the first share D. The re-computation controller issues re-computation orders to a computation platform to re-compute a part of the pre-computed search results, the part being selected by the re-computation controller on the basis of the validity probabilities associated with the pre-computed search results.
