Abstract

A method for retrieving calculation results, wherein a first input or selection causes a first calculation on a database to produce an intermediate result, and a second selection or input causes a second calculation on the intermediate result, producing a final result. These results are cached with digital fingerprint identifiers. A first identifier is calculated from the first selection, and a second identifier is calculated from the second selection and the intermediate result. The first identifier and intermediate result are associated and cached, while the second identifier and final result are associated and cached. The final result may be then retrieved using the first and second selections or inputs by recalculating the first identifier and searching the cache for the first identifier associated with the intermediate result. Upon locating the intermediate result, the second identifier may be recalculated to locate the cached second identifier associated with the final result.
