So...if the application works with the database in the application as 
designed, then it's okay with RS?

I would like to try working with an idea I'm kicking around, but I don't 
like the idea of designing something that would end up requiring the 
full SQL database in Pro and having a client purchase both the 
application and a license from RS for the database portion.  I can't 
find material that clearly defines under what circumstances the database 
in Pro vs. Standard would not be suitable for different purposes.
