SQXML Integration System

Many applications today need to retrieve and manage information from diverse systems and data sources, where related data is stored in quite different formats. Nowadays, enterprises often need to manage information both from XML documents stored in a native XML database system and from (object-)relational data stored in an (object-)relational database system. The idea of the SQXML project is to integrate these two information sources. The SQXML Integration System will provide the user with a global integrated schema that unifies the XML and SQL database schemas, so that the user will get an access to the entire information stored in these separate data sources. Both query languages, SQL and XQuery, will be supported in the global schema. At the same time the databases will co-exist independent from each other, preserving their autonomy. The project is aimed at investigating methods and techniques in the field of Information Integration and developing new concepts to implement the SQXML Integration System.
