摘要
Information-based decision support may be provided by a query handler configured to receive a query which is applicable against different combinations of a plurality of remote databases and a corresponding plurality of replica databases including at least some replicated data of respective ones of the remote databases, wherein each replica database is synchronized with a corresponding remote database at a plurality of synchronization times and the different combinations include future versions of the replica databases defined by corresponding synchronization times. A query plan generator may be configured to determine information values associated with at least a subset of the different combinations, based on a query value associated with the query and on a diminishment of the query value caused by a corresponding combination, and further configured to generate, based on the information values, a query plan including at least one combination of the different combinations for executing the query therewith.
