I have recently been given the task of making an online store, I have been able to do most of it, but I am stuck on what to do about sizes. The company I work for has bought inventory that is broken down by product and then sizes. There is a select number of items for each size. Should I be doing a seperate table that stores the product and sizes and subtract all from there or should it all be in one database? Any links, ideas... anything would be appreciated. I am hitting my head on a wall.
