A Framework for Distributed Query Processing Based on Web Services

摘要

With wider application of distributed systems,distributed database system techniques have been an important area for research in information processing. To reach a high level of accuracy,transparency,and optimization of distributed query processing,this paper proposes an infrastructure of distributed query processing system based on web-services,which has a multi-tier structure and improves the utilization of the system and obtain the transparency of underlying heterogeneous data resources. This system could provide efficient and intelligent query on distributed data resources and make users share heterogeneous data.
