每个类别的产品属性

Question

I have a category table with category id, name and parent. I have a products table with a link to the category table named cat_id .

Now I have diffrent kind of products and not every product has the same kind of attributes like colour or pieces. So my problem is: How to setup that I can have different attributes per category?

I am stuck at how I can best link this. Now I have a column in the products table with all the attributes, but also the ones that are not used per category.

Answer 1

Make an attribute category table:

attcat_id attcat_name

Make an attribute table:

att_id attcat_id (foreign key) att_name

This way these two will be linked

Now in category table associate each category with attribute category

cat_id cat_name attcat_id (foreign key)

So idea is to group attributes as per attribute category and link attribute category to Product Category. For example, an attribute category mobile will have attributes as price screensize camera flashlight .

Now link mobile ie attribute category to your product category Mobiles .
