Franconi, Enrico and Kuper, Gabriel and Lopatenko, Andrei and Zaihrayeu, Ilya (2004) Queries and Updates in the coDB Peer to Peer Database System. UNSPECIFIED.
In this short paper we present the coDB P2P DB system. A network of databases, possibly with different schemas, are interconnected by means of GLAV coordination rules, which are inclusions of conjunctive queries, with possibly existential variables in the head; coordination rules may be cyclic. Each node can be queried in its schema for data, which the node can fetch from its neighbours, if a coordination rule is involved.
