Development of an XML Query Interface to Support Integrated Queries for Biological Information Sources

An XML-based mediator system is the one of the methods to virtually integrate distributed heterogeneous information sources. It considers each information source as the virtual XML database and accesses the information source by XML query language. In this paper, we present a design concept and a development result of the graphic user interface that generates XML views for each biological information sources with flexibility and XML queries on the views. In addison to the easy generation of XML views and queries for the integrated schema, the system supports the form of the workflow, in which the part of the query result against biological information sources is used as input data of an another source.
