I haven't followed the thread in detail, so apologies if this was already
covered, but FWIW, when I had to design a db layer, I used

Connection conn = createConnection( "mysql://user:password_at_host/database" );

The advantage of this approach is that the URL-like thing can come from a
configuration file, so you don't need to recompile to change the backend. In
a typical scenario, createConnection would need to look for
backend_mysql.dll/.so unless the support for the 'mysql' backend has been
statically linked.
