High performance Grid computing provides an infrastructure for access and processing of large volume, terabyte or even petabytes, of distributed data. Research in data grid has focused on security issues, resource ownership, infrastructure development and replication issues assuming presence of single transaction in the system. In this paper we highlight(More)
