Make Cade's class diagram

[Joseph Zhou]

In Make Cade's class diagram, there is an unidirectional association from Product to ProductCategories. if that is the case, how canwe make product search in the ProductCategories?

Hi,
I think Product must contain a Product Category key, so the search can be done within Product.

Hi Ray,

Thanks a lot for your reply. I still not quite understand. usually, we search product(s) in categories, that means a category hold a set of product keys. if a product hold category keys, how can we make it useful?
