A Case Tool for Designing XML Views.
Ya Bing Chen, Tok Wang Ling, Mong Li Lee · 2002
XML views are essential for managing XML data on the Web. Like views in traditional databases, XML views allow users to see data from different perspectives. Moreover, XML views are able to offer a structured interface over semistructured data and make it possible to integrate heterogeneous data source. In this paper, we describe a graphical case tool for designing XML views with the following novel features. First, it supports validation of views by checking if a view conforms to the semantics in the underlying source schemas. The feature is critical for XML views design because it avoid producing meaningless views. Second, the case tool provides a scheme to store XML data into an object-relational database that reduces redundancies and facilitates efficient processing of queries over XML views.
