Querying relational databases through XSLT

摘要

XML has been accepted as a universal format for data interchange and publication. It can be applied in the applications in which the data of a database needs to be viewed in XML format so that the data being viewed takes more semantics and is easily understood. In these applications, the user of the data to be viewed sees only XML data, not the database. He may use XML query languages such as XSLT, XQuery, and XML-QL to query data and the retrieved data is presented in XML format to them. We are interested in the connection between the data that the user sees and the data in the database. More specifically, we are interested in translating XSLT queries to SQL queries which are for relational databases and in wrapping the data retrieved from the relational database in XML format.
