Is there a way that I can make a direct link to a grade table and a Microsoft Access Database?
I would not recommend this but technically it could be possible, but may make your system non-compliant with support. I don't know if this is the case or not, but just a forewarning. You would have to work with your system's administrator as well. For example, I know you can use Access to connect and pull data from an Oracle or SQL Server database through an ODBC connection and that's what is in Blackboard's backend.
