Contribution

It introduces a novel approach for approximate query processing that balances response time and accuracy for flexible SQL queries with joins and groupings.

Findings

Reduces query response time significantly

Maintains acceptable levels of result accuracy

Applicable to complex SQL queries with joins

Abstract

This paper addresses the problem of approximate processing for flexible queries in the form SELECT-FROM-WHERE-GROUP BY with join condition. It offers a flexible framework for online aggregation while promoting response time at the expense of result accuracy.
