[@evansgrahamdonkor161]

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!

This 12-minute video taught me better than my 4-hour Zybooks lesson on this topic. Thank you so much.

Hello professor!! I have a midterm tomorrow and I wanted to say thank you for creating good and understandable content. it is hard enough to find KZbin videos on uni courses so I appreciate your efforts. :) It was very helpful.

Hi Dr. Soper, at 10:55 the slide says the the maximum cardinality for Order is many and one for Customer. Shouldn't the maximum cardinality of the Order be one and many for the Customer? Because cardinality for the Order entity set tells the number of times each Order entity can participate in this binary relationship; in other words, the cardinality for the Order entity set tells how many entities from the Customer entity set can be associated with each Order entity. Going by this way the maximum cardinality of Order should be one and many for the Customer. Please let me know if I am wrong. And thanks for your wonderful videos on Database concepts.

[@angusratcliffe4525]

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.
