advice on a Rev-plus-internet setup (off-topic)

I must be missing something here.  Why do you need access to the 
DATABASE from the web?  All you need to do is make "requests" to the WEB 
SERVER where a cgi program will do the talking to the database.  The 
database itself is never exposed to the outside world.  You need NO 
database drivers in the program that is installed on the user machines.  
As far as they are concerned, they are accessing a text file.  How that 
text get retrieved doesn't matter to the program.

What am I missing here?
