Getting ready to setup a database for selling stuff

[Mark Roberge]

HI,
I have a great deal of experience working with mysql, but now I want to make a database that works. I am thinking that I need two tables. The first one has all of the customers info. The second one I am calling inventory. Now in the inventory table I was thinking that I will use foreign key, item 1 price 1, item 2, price 2 item 3 price 3. Will this work? Do I need to break down table to be something like this instead, item 1 price 1, new table item 2 price 2?
Your help is appreciated, So which do I use?
