Claim One:
1. A machine-implemented method to execute on processing devices, comprising: initializing, using an aggregate user-defined function (UDF) on each of the processing devices, an intermediate storage structure to house regression input variables on each of the processing device of a database environment; gathering, using the aggregate UDF on each of the processing devices, data from a database into the intermediate storage structures on each processing device; merging, using the aggregate UDF on each of the processing devices, year week data pertaining to a same product stock keeping unit (SKU) found on each of the processing devices together, via the intermediate storage structure; placing, on each processing device, merged year week data of the same product SKU; and processing, using the aggregate UDF on each of the processing devices, a regression service for each SKU on each processing device.
