A Query Algebra for XML P2P Databases

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

Abstract

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.
