You don't need a database for what your talking about. There is a couple different ways to implement it depending on the languages you choose to use. 1. you can use javascript and have an edit button on the page/section you want to be editable
2. have an outside page that actually edits the sections of the page you want to be editable...
Either way you would have to have some sort of protection from it allowing just anyone to edit the pages such as a login system...
I wrote a script a while back to do exactly what your talking about and I use FCKeditor in it...PM if you want to use it.. but its
PHP based so your server would have to have
PHP installed.. but it uses a flatfile db so you dont need mysql or anything.

I never finished changing the things I wanted to but its still usable.
