This paper presents a query interface that talks to a mediator system based on XML data model. Due to using XMLView concept, a mediator system considers every biological source as an XML document. Therefore, the user makes query and search to the XMLView and in addition to receives an XML document as a result.
A query interface graphically presents biological sources in the integrated system as tree structure and processes the user query as workflow. A query interface has two major functions. First, if the user inputs search conditions and keyword, a query interface automatically makes XQuery and sends it to the mediator. second, it is to execute query sequencely among the sources. If the source frames are connected with lines, the search result in pre-source sends to the next source then automatically add to the next query.
