Wayne,
In your blueprint --> Management --> Data Management --> Right Pane --> Add Database --> Enter Credentials \ Info --> Save
Then
In your blueprint --> Configuration --> Configuration Data --> Right Pane --> Select the Server Name you added above --> Save
IF Then you need Database Info then
In your blueprint --> Configuration --> Configuration Data --> Right Pane --> Database Server --> Add Query --> Enter the info you want to obtain
A good blueprint example to follow is "CA Unicenter Service Desk(Windows)" and "CCA Server" (they are slightly different from the instructions above, but that's the general concept"
Please let me know if that is what you were looking for
