Database techniques generally require the reading of complete rows of data (traditionally referenced as “records”) in order to get at a single attribute that might be of interest. Further, if filtering is required (not all records are of interest), a further computational step is needed on each record to determine if it qualifies. Transposition of the data enables this to be accomplished with a single read operation, followed by a single filter-pointer operation producing essentially instantaneous results. This method has proven successful in producing real-time instantaneous results when applied to well over millions of records.
