Abstract
A data processing system (10) comprising a general purpose computer (20) for carrying out database processing operations. An aggregation system (30) is in communication with the general purpose computer (20). The aggregation system (30) includes a memory (32) for storing, for each of a plurality of data values, a base value and one or more incremental updates. An aggregation processor (34) forming part of the aggregation system (30) receives the incremental updates from the general purpose computer (20), writes the incremental updates into the memory (32), and controls the aggregation of base values and incremental updates stored in said memory (32) to read the data values. In this manner data values are updated and read without the use of locking operations.
