Gerard,

With MM, this is easily accomplished using database sets, each potentially with its own data access class. All of this is set in the app.config file

Follow my signature link to Oak Leaf Enterprise's homepage and download the latest developer's guide. See the "Specifying Connection Strings and Database Settings" child node of the "Data Access with Business Objects" topic for specifics.

Hope this answers your question,
