Table Relationships - how to do

Navigation
1

I'm having trouble understanding how to create the relationship of the tables. My scenario is as below:

A parceiro can have multiple usuários , but a usuário can only be linked to a parceiro . A usuário can register countless pedidos , and those pedidos will be linked usuário that registered and parceiro of the user. Example:% with% a is linked to pedido cesar in which this usuário is linked to usuário partner x .

To make a new parceiro it is necessary to put the code (id) of pedido and the data of the new request, such as: name, rg, cpf and email

In this parceiro there is a pedido in which it is unique and being formed by cpf-partner . In a table chave de vpn has the vpnCode , bytes received, sent, server ip, real ip.

A chave de vpn has VPN , chave de vpn that generated it, parceiro cpf , pedido rg .

What I can not understand (I've been trying to figure out how to do it for more than a week) is how to make those relationships. Please, I need help.

I think this architecture should solve your problem. I did not put all the VPN fields but you can do it yourself.
