QoS control based on query response time prediction
Mario Miličević, Mirta Baranović, Vedran Batoš · 2005
Warehouse (DW)) is determined with a response time, availability, consistency and currency. In this paper we consider the influence of the system load and the system throughput on the response time, as well as a possibility of the accurate response time prediction- whereby that mechanism may be a foundation for (automatized) decision-making for a query (or DB procedure) scheduling. The possible application of proposed method can be the estimation of the optimal moment for the data transfer from OLTP system into DW or the appropriate moment for the complex query execution.
