What ILMV is trying to explain is that you have to have HTML pages that Google and other search engines can 'crawl' in order for them to index your content.
Since your information is loading dynamically from a database, you will need to use a server-side language like PHP to dynamically load information from the database and then output that information to an HTML page.
You have any number of options for how to accomplish this specifically, ILMV's suggestion is one of the better ways though.
Basically what you need to do first is figure out how to pull the information from the database and then use PHP (or another server-side language) to output the information to an HTML page.
Then you will need to determine whether you want to use the uglier, default url style for php driven pages:
mysite.com/products.php?id=123
But this url is not very user or search engine friendly and will result in your content not being indexed very well.
Or you can use some sort of URL rewriting mechanism (mod_rewrite in a .htaccess file does this or you can look at more complex PHP oriented solutions like Zend Framework that provide what's called a Front Controller to handle mapping of all requests) to make it so that your url's look like:
mysite.com/products/123/nice-bmw-m3-2006
This is what ILMV is talking about with regard to url masking.
Using this method of dynamically loading content will allow you to develop a single page to load the information for a number of different products based on the Id thus making it seem to the various search engines as though you have a unique page for each product.
