Aggregate Queries in Peer-to-Peer OLAP ering each node as a peer in a cooperative query system, and allowing each peer a high degree of autonomy. Each node involved in the system defines a context where it be-comes the local peer, and all its dimensions and fact tables are considered local henceforth. The rest of the nodes that connect with the local peer, are considered acquaintances

Abstract Peer to peer databases are becoming prevalent on the Internet for distribution and sharing of documents, applications, and other digital media. The problem of answering large-scale ad hoc analysis queries, such as aggregation queries, these databases poses unique challenges. R. Saravanan, P. Vivekananth 2012CiteSeerX — Aggregate Queries in Peer-to-Peer OLAP A peer-to-peer (P2P) data management system consists essentially of a network of peer systems, each maintaining full autonomy over its own data resources. Data exchange between peers occurs when one of them, in the role of a local peer, needs data available in other nodes, denoted the acquaintances of the local peer.

A Novel Efficient Approximate Query Processing In P2P Network a) In pure peer-to-peer network peers act as equals, merging the roles of clients and server. In such networks, there is no central server managing the network, neither is there a central router. Some examples of pure P2P Application Layer networks designed for peer-to-peer file sharing are gnutella (pre v0.4) and Freenet.

Nodes at depth 2 will not process the query, but will forward the Query message to depth 3. Eventually, nodes at depth 5 will process the query, since depth 5 is in the policy.

Real Datasets for File-sharing Peer-to-Peer Systems ministration. One major drawback, though, is the query processing protocol; whenever a node receives a query message, it broadcasts it to all of its neigh-bors. This is done recursively until a maximum number of hops is reached. This algorithm does not scale well to a large population size, since the whole network is overwhelmed with query messages.

When a peer intends to query the global reputation of another peer, it will broadcast the query message; when a peer wants to report its feedbacks, it will broadcast the reports. This method will impose a lot of message in the network. Besides, when network size is very large, it will take a long time to disseminate peer reports and to get a
