Owenship/Agent companies), the only thing i was told when i started
designing the DB/Apps was just one company.
So i built everything into one single

how about having a company table, and company_code column across all relevant table, although you'll have to modify your application also, which would be an additional clause in the WHERE condition e.g where company_code = 'which company user has logged in'.
The user has to specify while logging u

What is the easiest way to migrate a complete database from one
