Relational database for address model

I want to design an "Address" model for all types of entities like users, businesses, etc. I have two types of main models: one is User and the other is Business. Each one has different address types like below. ### User 1.Contact Address 2.Billing Address ### Business 1.Contact Address 2.something So I created an address model with an addresstype column like this ### Address id addresstype user addressline1 addressline2 Relationships: * User – One to many –> Business * User – One to many –> Address (User Column) Now using the above relations, addresstype and user columns will be in a relation, but Business address is not relatted with address. How can I design this one in an efficient way?
