it uses the same DB, Question?

don't understand your question

... if both installations are using the same one database, you will see database changes in both installations ...
So another funny thing is possible too:
Make one cmsms installation on your internet server and one cmsms installation on your local server (xampp or so other). If your provider allow this and you change the config.php of your local installation to the right values you can write with your local installation to your internet database without access to your internet cmsms installation
