I am modelling a database for use in a sql only application for now.
I have three tables
Company
company_id,name
Contact
contact_id, name
rel_contact_company
company_id, contact_id, is_employee
It’s a many to many relationship but the relation ship table has extra information about the relationship (is_employee).
Is it possible to query this information from jdo using normal relationships or is it better to create two relationship tables?
