Materialized views for P2P XML warehousing
Ioana Manolescu, Spyros Zoupanos · 2009
We consider the efficient, scalable management of XML documents in structured peer-to-peer networks based on distributed hash table (DHT) indices. We present an approach for exploiting materialized views deployed in the DHT network independently by the peers, to answer an interesting dialect of tree pattern queries. We provide algorithms to index and materialize views in the DHT, show that the rewriting problem is polynomial in the number of views, and describe rewriting algorithms. Our approach is validated by experiments on the complete platform deployed on 1000 peers in a wide area network.
