Abstract: - In decision support activities, it is very important to provide the user with feasible strategies to answer complex queries, besides furnishing fast query response time. The alternative to the time-consuming scan of huge amounts of data in data warehouses is provided by the use of data reduction for data analysis and a suitable approximate query processing strategy.
