Database Design

[[Mystic]]

Hi guys

I was just wondering, im designing a shopping cart for my own site using
php/mysql.

I have my design like this. I have one table for the protuct that has a
collum for product type. Product type is another table that has links to
other tables like motherboards, hard drives etc. I hope you understand this.
Is that the easyest, most efficent way to do it?

Thanks
