Triple many to many relationship
Friends, I am having difficulty creating a relationship of tables in a database.
I have a table and another table technology company. For each technology has several companies,
and for each company have different technologies. A many to many.
I created a join table to resolve this issue, with two foreign keys.
I have another table Product, and for each company I have several products, and for each technology I also have
various products.
Any help is welcome.
Thank you.
