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the computation platform and is configured to determine probabilities of the pre-computed database query results being outdated, to automatically issue re-computation orders to the computation platform for updating pre- computed database query results on the basis of the determined probabilities of the pre- computed database query results being outdated and to receive the updated pre-computed database query results as results of the re-computation orders.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 database query results maintained in the data cache platform and presumed actual database query results.
