thanks man. We pay tuition to universities but the actually teaching and learning goes on here for free. Such a funny world we live in.

It seems like textbooks intentionally try to bewilder the students rather than teach something. Your explanation is impeccable!

Hi, I'm guessing that the focus of these relationships is between the primary keys of different tables and that is what defines the type of relationship? For example, the customer table would contain much more information on different purchases and maybe personal information, but the relationship we are describing is between the customer ID and the primary key in another table, i.e. order ID.
