Distributed Online Aggregations

To answer an aggregate query, a large proportion of the databases needs to be accessed. Compared to non-aggregate queries, aggregate queries are expen-sive and require long processing time. While parallel and/or dis-tributed processing techniques can be employed to speed up the processing of such queries, the users may still find the long waiting

Improving Search in Peer

When a user submits a query, her source node sends the query message to a set of its neighbors. The routing policy determines which neighbors (possibly all) are in this set. When a node receives a Query message, it may forward the query to a set of its neighbors, depending on the routing policy. The node will also process the query over its local
