I am a newbie at web programming and dotnetnuke.  We are thinking of migrating a desktop app to dnn.  We already have a  database with tens of thousands of records and I would like to keep this database separate from the dnn database.  ( if in the future we would use some other platform I would like to have the data be separate) Is there a way to program a dnn module to access a database other than the dnn database that was created when dnn was installed. So the portions of the website that are common to all dnn websites use the dnn database but my custom modules would use a different database.

Thanks so much
