I have a database called “Services”, it’s a list of services. The new users have to select services they want to propose and add their own price. Each user may have a different price. I’ve tried to create a price database related to users and services but the relationships did not seem to work because users can I have multiple prices but a service can have one price and vice versa. I was thinking that the right answer is to add a property to the service database and to make ii particular for each user, but I don’t how I can do that.
