I tried to delay asking this question until the upcoming training session, but I need to determine if the following setup scenario is possible without having to purchase the middle-tier app server product.

The majority of our customers operate in the typical client workstation / database server environment. Can I install my Business Object Library and Data Access Layer on the database server and install the WinForm UI on the workstations? If so, how do I accomplish this? 

Thanks,

Tim

No, since the business objects bind to the user interface, your client app will need to reference the Business Object Library.  The business objects are serializable, so you could write your own marshalling tier that would marshall calls back and forth between the app server and the UI, but that would require a great deal of custom code.  Incidentally, the middle-tier enterprise server is designed to be placed between the DAL of the client and the database server to act as a proxy for the database requests.  No processing is done on the enterprise server other than the actual database requests themselves.
