Android room schema relation

Question

With my android room database, I have 2 tables: order and service , where service is either: massage, haircut, or spa. An order could have 1 or more services, I want my service table to just have my 3 different services. What is the right way to do this?

Should I be using join ? Foreign key ? @relation ? embed ?

I don't want any copies of services in my order table, because the detail/price of service could change at any time.

Answer 1

You should just use foreign key for 1 to many relation (one order : multiple services). This may help you and here is official documentation.
