OLAP query algorithm based on real-time semantic dimension hierarchical
Fu Ming · Computer Engineering and Applications Journal · 2012
Nowadays,the result of OLAP query obtains from all other clients. For example:DSCD algorithm and DQDC algorithm aim to research the way to get the result of querying quickly,However,Data Cube in other clients can not be updated on real time. So it is easy to lead the result of query distortion. It has an effect on the efficiency of OLAP. In order to improve the efficiency of the realtime query of OLAP,this paper proposes a real-time semantic OLAP search algorithm. Through the experiment,it unifies the results of inquiry speed and distortion rate of two aspects,demonstrates that the RTOS algorithm can effectively improve the OLAP decision analysis performance on the P2P environment.
