A Query Algebra for XML P2P Databases

  • Carlo Sartiani
Part of the Lecture Notes in Computer Science book series (LNCS, volume 4254)


One missing point in the current research about p2p XML databases is the definition of a proper query algebra that addresses p2p -specific issues, such as the dissemination and replication of data, the dynamic nature of the system, and the transient nature of data and replicas.

This paper describes a query algebra for queries over XML p2p databases that provides explicit mechanisms for modeling data dissemination and replication constraints.
