The Codb Robust Peer-to-peer Database System

Year: 2004

Type: article

Abstract: In this paper we give an overview of the coDB semantically well-founded P2P DB system. A network of databases, possibly with di#erent 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. Correctness and termination of query answering is guaranteed also in the case of runtime change in the topology of the network.
