The e-commerce.

database structure, explain of some tables


Recommended Posts

Hi guys,


I am posting a question to which I did not found response until now.

I am rewriting our company database in order to conform to the structure of oscommerce. We will use Postgresql then and i do not have access to Mysql database.


My question is: what is the "product_option_values_to_product_options" table? is it a join table for a relation many-many? Or is it a validation table that provides the options for "product attributes table"?

I do not understand, but this may be related to my limited experience in database design. I created the tables product options and p.o.values , i set the relationship between them and "P.O to P.O.V" then I created product attributes believing that in this Way I could only choose an already set record but it is not working in this way (I can choose whatever combination i want, i.e. color and 64 mb) Could you please explain me better?


Sorry for my inexperience and for my english.
