1. A method of processing transactional data for use in accordance with a decision support operation, comprising the steps of: transforming the transactional data into an interim form according to a relative importance of the transactional data to the decision support operation; and incrementally analyzing the transformed transactional data, wherein the step of incremental analyzing comprises applying a successive approximation to the transactional data in the interim form, wherein the decision support operation is incrementally performed based on a transactional load; wherein the transforming and incremental analyzing steps are executed on a computing system comprising a processor and a memory, wherein one or more software components for implementing the transforming and incremental analyzing steps are loaded from the memory and executed by the processor.
