 The normal way for Delphi and Kylix is just to check dbExpress,
 put a TSQLConnection on a form then double-click the TSQLConnection to display
 the Connection Editor and set parameter values (database path, connection name etc.)
 to indicate the settings.
 But in our example, all goes by runtime (path and login) with dbExpress we don't need
 an alias or the BDE either.
