Quality Control Inspection Team cost model that takes the complex structure of queries on XML data into account. We show that system performance can be improved after vertical fragmentation using our approach, which is based on user access patterns.

Construction Products Liabilityntics of their data and organizing the clusters into semantic routing overlays, an efficient query-routing algorithm can be used among these clusters. Preliminary evaluation indicates that our approach achieves a competitive trade-off between search latencies and overheads, and load-balancing among super-peers is well maintained.

Introduction to the European Communityplacement in tree, Peer-to-Peer (P2P) and hybrid architectures. Beside tree model which is being implemented for many Data Grid applications, hybrid and P2P grid models of replication are also emerging for providing scientific communities with better availability and efficient access to massive data.

Third, it creates an executed plan of optimum composition on Grid. We conducted experiments to simulate and evaluate our approach.

In addition, the priority levels of queries can be guaranteed by GM. The experimental results indicate that the GM scheduling strategy is very effective in practice.

Cost Framework for a Heterogeneous Distributed Semi-structured Environmentogeneous and autonomous data sources. Our approach relies on cost annotation on an XQuery logical representation called Tree Graph View (TGV). A generic cost communication language is used to give an XML-based uniform format for cost communication within the XLive system. This cost framework is suit

Cost-Based Vertical Fragmentation for XMLchallenging question is how to manage native XML data in distributed databases. This leads to the problem of how to obtain a suitable distribution design for XML documents. In this paper we present a design approach for vertical fragmentation to minimise total query costs. Our approach is based on a
