Product database

Hello there,

I am going to write a product database for our phone site. We already have our tables and the fields. Actually, we just can start entering a product into the database. My question is — I really do not have an idea — how can I display them publicly?

First: I would like the call each product through a slug, not like this: http://mysite.com/products/id=123456. I rather want this: http://mysite.com/products/nokia-lumia-925 or http://mysite.com/products/apple-iphone-5

So. How do I display them and how can I WordPress tell, that this URL referers to product XYZ?

These are my questions for the start. Thank you guys!
