I have a case where a company has multiple branches with different addresses and each of these branches rely on the same accounting book (each branch has the same tax id as the main company). So in such case,  working with Odoo version 12, I would like to know in which table the branches of a company are often stored in Odoo dbms?

In odoo, res.company has the structure to store the child of a company but is this intended for storing the companies of a multinational company (with different tax ids and accounting books) or used for storing the branches? Is there any standard Odoo approach for storing this (branches) in the dbms?
