Abstract
A pre-computed result module computes a result prior to receiving a query. The pre-computed result module includes instructions executed by a processor to assess a pre-computation query to designate each identified database source that contributes to the answer to the pre-computation query and corresponding database source metadata. A metadata signature is computed for each identified database source to create a store of identified database sources and corresponding metadata signatures. The query is evaluated to identify accessed database sources responsive to the query. A current metadata signature for each accessed database source is compared to the metadata signatures to identify each updated database source. Re-computed results are formed for each updated database source. Pre-computed results are utilized for each database source that is not updated. A response is supplied to the query using the re-computed results and the pre-computed results.
