Processing and Optimization of Complex Queries in Schema-Based P2P-Networks
Peer-to-Peer infrastructures are emerging as one of the important data management infrastructures in the World Wide Web. So far, however, most work has focused on simple P2P networks which tackle efficient query distribution to a large set of peers but assume that each query can be answered completely at each peer. For queries which need data from more than one peer to be executed this is clearly insufficient. Unfortunately, though quite a few database techniques can be re-used in the P2P context, a P2P data management infrastructure poses additional challenges caused by the dynamic nature of these networks. In P2P networks, we can neither assume global knowledge about data distribution, nor are static topologies and static query plans suitable for these networks. Unlike in traditional distributed database systems, we have no complete schema and distribution instance available but rather work with distributed schema information which can only direct query processing tasks from one no...
