A middle layer for distributed data warehouses using the DWS-AQA technique
Authors
Abstract
The DWS (Data Warehouse Striping) technique is a round-robin data partitioning approach especially designed for distributed data warehouse envi-ronments. In DWS the fact tables are distributed by an arbitrary number of computers and the queries are executed in parallel by all the computers, guaran-tying a nearly optimal speed up and scale up. This technique is combined with an approximate query answering (AQA) strategy to deal with fails in one or more nodes. This paper presents a middle layer software and administration tools allowing the transparent implementation of DWS-AQA in commercial da-tabases and OLAP (On-line Analytical Processing) tools.Keywords
