Hi Bruno,
We inform you that Olap providers could establish a connection from the database only if the Cube Schema is mapped with that. Once you have a proper plan of your cube schema, you can use this schema with any of the OLAP/Xmla server like Analysis Server, mondrian server,Hyperion server,Oracle Olap server.
Please refer the following links to define a Cube Schema .
