how do i make new webpages with the fckeditor

Anyway so i know how to edit pages with fckeditor however i cant figure out where its saving the webpages. I notice it uses the updatepage.php file and the page.php file but i cant figure out where its saving the ids. for example http://www.randompage.com/page.php?id=6 or http://www.randompage.com/updatepage.php?id=6
i can find the page.php and the updatepage.php but i cant find where the id is stored so i can add more.
i believe it saves to an sql database but i cant find it either.
