Insertion and querying mechanism for a distributed XML database system

XML files are ideal for describing semi structured data. The advent of native XML databases has enhanced storage of a large number of XML files preserving the hierarchical format. The challenge is to serve and access XML data from geographically distributed native XML databases. In this paper, we discuss the modus operandi for insertion and querying of data in a location transparent manner in decentralised networks. We present the design for a cluster based architecture where query processingF is achieved using distributed hash tables. A bulk insertion method has been employed for insertion of XML data. The proposed design was implemented on eXist-db, a native XML database engine. Experiments were conducted and the effectiveness of the proposed design was evaluated.
