One to Many
What makes each piece of equipment with the same name, unique per customer?
An item of Equipment is "Generic" Eg. Ford falcon - until linked to a customer. Once linked the specific item can be given a Registration number or Serial number to make it Unique.
In this example you may have 20 Customers with a Ford Falcon but Ford Falcon would only appear in the Equipment List Once. It would however appear in the Customer Equipment List 20 times - Once for each customer.
