What is the best way to make a multi lingual site?

hi,

I need to do a multi lingual site (for now it is 2 languages but can grow).
I want to have only one button on my master page that will switch from one language to the other one.
(lets think of it for now as 2 languages site).
also I want all the data to come from a database, so the admin could change the contents of his site in the admin pages.(even textual data).

what is the best way to do it?

thanks

Hi

Use satellite assemblies... Using it you can easily manage multilingual sites with any number of languages..

but can the admin change the contents of his site(dynamically) from the site itself without touching the assemblies?
Satellite assemblies are fine if you are sticking with given set of lanuages. Once you implement it you are taking away the option of modifying the text (wihtout source access) since it gets compiled.
I'd interested if anyone implemented some other solution that would allow you to public a language file that will not get compiled. I'm thinking an XML file, cahce it, read it and do yout translation that way.
