Question

For example, I have two tables.

• Name: Customer
• Primary key: idCustomer
• AnotherColumn: name
• Foreign key: idVendor

Another table:

• Name Vendor
• Primary Key: idVendor
• AnotherColumn: name

I want to create 1:n relation.

Which table is a primary key table and which is a foreign key table?

Answer 1

I think what you mean is which is the 1 and which is the n. The 1 would be vendor the n would be customer. you can have many customers to one vendor but only one vendor per customer.
