I have seen websites seeming to use mod_rewrite to rewrite their URL's and they look like this:
http://www.somewebsite.com
The only way I know to do URL rewriting produces this:
http://www.somewebsite.com
How is the first result produced? Do they have a script that writes directly to the .htaccess file?

Also they may be using URL rewriting via Apache to convert the URL into something like
http://myDomain.com/index.
at which point looking up the database becomes a trivial issue. The mod_rewrite rules for Apache for here http://httpd.apache.org/do
RewriteEngine on
RewriteRule ^/([a-zA-Z]+)/[-a-zA-Z0-9]
It could be anything. By using mod_rewrite's regex capability you can pick up whatever you desire. For instance, to limit "slug" to just numbers I would change it from
RewriteEngine on
RewriteRule ^/([a-zA-Z]+)/([-a-zA-Z0-9
to
RewriteEngine on
RewriteRule ^/([a-zA-Z]+)/([0-9]+)\.ht
I've also just noticed a missing bracket in the original post which I have corrected. I have not tested these actual expressions posted here so if you use them you may have to tune them a bit. I was only attempting to illustrate the point but they should not be correct or very nearly so.

Chances are, they're just using a unique search key as the field to search on.
For example, you can create a "slug" field in your products table and set it to UNIQUE.
In your example, the product slug could be "Some-Product". As long as no other product has the same name, you will always be able to uniquely search for that product. Text searches won't be as fast as ID searches, but you'll still be able to select products by that field if you want a URL without an ID.
