As the Oracle connection is handled in via the Oracle libs in the Baan database driver is created by Oracle devilers itself, the Baan driver can connect to any other Oracle database on whatever platform.
But, if only a few queries are to be expected it is of course possible to use some Baan tools to query and format the database on whatever you need.
Hope this helps,
