In this paper, we address the problems of adaptive schema mappings between different peers in peer-to-peer network and searching for interesting data residing at different peers ba...
Cache groups are a powerful concept for database caching, which is used to relieve the backend database load and to keep referenced data close to the application programs at the &q...
In mobile ad-hoc peer-to-peer (M-P2P) networks, a large percentage of the mobile peers typically do not provide any service to the network, thereby motivating incentive schemes for...
Abstract. We have defined an XML structural index called the Structure Index Tree (SIT), which eliminates duplicate structures arising from the equivalent subtrees in an XML docume...
Data on the Web is increasingly being used for discovery and exploratory tasks. Unlike traditional fact-finding tasks that require only the typical single-query and response parad...
Substructure similarity search is to retrieve graphs that approximately contain a given query graph. It has many applications, e.g., detecting similar functions among chemical com...
Query mapping to aggregation lattices is used in order to exploit sub-cube dependencies in multidimensional databases. It is employed in mobile OLAP dissemination systems, in order...
: Relational database systems are highly efficient hosts to table-shaped data. It is all the more interesting to see how a careful inspection of both, the XML tree structure as wel...
