Abstract

Many of today's middleware solutions employ XML to resolve heterogeneities and to create an interoperable layer between sources and systems. However, XML performs poorly when queried in its native format, and local and global views are not supported by current XML products. In this paper, we support the concept of data everywhere by providing a view mechanism for XML together with a highly-optimised query processing strategy.
