Metrics for approximate query engine evaluation
Francesco Di Tria, Ezio Lefons, Filippo Tangorra · 2012
The performance evaluation of the transaction processing in Database Management Systems used for Decision Support Systems is the aim of the current TPC-H standard. Decision Support Systems also include Approximate Query Answering Systems. However, the TPC-H does not define a methodology to evaluate these systems, nor does it provide useful metrics. In this paper, we address the problem related to the extension of TPC-H, in order to adjust it for the performance evaluation of the engines used in approximate query processing to provide fast and approximate responses to analytical queries.
