Abstract:
Peer to Peer system extends ideas about
distributed computing and client server computing,
blurring the distinction between clients and servers.
The P2P paradigm was recently adopted in the
database community to overcome the limitations of
distributed system, namely the static topology and
the heavy administration work. XML databases are
widely used for P2P system. Query processing over
the P2P database faces many challenges and
problems. This paper presents design and
implementation of the distributed XQuery processing
over P2P system. The system can dynamically
execute distributed XQuery over the P2P system.
Query processing is dynamic and designed to reduce
network traffic because it only forwards partial
results that are needed by the neighbor peer instead
of every result. Each peer in the system has the query
processing capabilities and its own catalog. This
paper presents the design and implementation of the
Peer–to-Peer query processing system using XML
database. This system uses hotel and resort
information system as a case study.
