Topic 04, Part 08 - Crow's Foot Symbols with Cardinalities 

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!

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 RU-vid videos on uni courses so I appreciate your efforts. :) It was very helpful.

This makes so much since, thank you!

Best explanation I have heard. Thank you, Sir!

Explained better than my University Instructor

Thanks a lot sir. I was studying a book but I was not understanding this topic a model picture of ERD in my book. You have described those symbols very easily.

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.

Thanks for explaining the topic
