If you installed DevForce (DF), we tried to add it to your local SQL Server instance.
The tutorial database consists of two files:
NorthwindIB.mdf and
NorthwindIB_log.ldf. You should be able to find them in your SQL Server data directory (whose location depends upon your installation of SQL Server) AND in your DF installation directory, e.g. C:\Program Files (x86)\DevForce 2010.
The "Installation Guide" (Windows menu | DevForce 2010 ... | Documentation | Installation Guide) explains how to find and install it.
There may be a copy of the tutorial database online but we'll have to get back to you about that; I'm not sure where it is and if that one is up-to-date.
