Query Result Caching in Peer to Peer Networks UMD

590M entries would have to be scanned leading to a high processing cost per query The overhead hence either in terms of bandwidth if Bloom lters are not used or processing if Bloom lters are used especially multiplied over billions of queries is prohibitive We address the shortcomings of the above approach by using result caching

Query Translation in Database sharing Peer to Peer networks CORE

Abstract In a peer to peer database sharing network users query data from all peers using one query as if they are querying data from one database Implementing such a facility requires solutions to the problems of schema conflicts and query translation Query translation is the problem of rewriting a query posed in terms of one schema to the query
