We present an architecture for a data sharing peer-to-peer system where the data is shared in the form of database relations. In general, peer-to-peer systems try to locate exactm...
Unstructured peer-to-peer infrastructure has been widely employed to support large-scale distributed applications. Many of these applications, such as locationbased services and m...
Abstract-- This work presents a novel index structure, MHRtree, for efficiently answering approximate string match queries in large spatial databases. The MHR-tree is based on the ...
