We have a local relational database (Oracle 8i) in our lab.  We want to add 
other remote databases which will be stationed at remote places. These 
remote databases will be queried through an HTTP request.  Also, these 
remote databases could be any of flat file, XML database or relational.  We 
will construct a global XML schema that represents all these databases 
(local and remote). The global schema will then accept an XQuery.

We need a middleware system, that can do the following :
1) convert this XQuery into SQL - and query the local Oracle database.
2) Query the remote databases
3) Integrate the resultsets received from all the databases.
4) Return the XQuery result in XML format.

Does anyone know of a middleware that can accomplish the above.

thank you
