Abstract
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 may be defined by (1−acc)·t, wherein acc is a probability that the associated prepared result is valid and t is an age of the associated prepared result.
