Abstract
To make use of the recent distributed OLAP environment, researches on P2P (Peer-to-Peer) OLAP with the dynamic hybrid tree (DHT) and Grid OLAP are actively proposed. In addition, OLAP query execution costs many minutes by its enormous data and OLAP query properties. To adapt OLAP systems to the cloud computing environment, P2P OLAP has problems on executing multi-dimensional range queries because of P2P properties. In this paper, the central management Cloud P2P OLAP is proposed to provide an efficient cloud computing environment which query results are able to be reused with the time-series properties by various users. The Cloud P2P OLAP is grafted onto hierarchical hybrid P2P for fast query results and multi-dimensional range query, so that the index loads are distributed and the performance is improved.
