Dude, you could definitely get a teaching job if you wanted to.
You're one of the best teachers i've ever had. You use humour, creativity, story-telling and you have a contagious enthusiasm for what you teach. Good stuff and more power to you
Yeah this guy is soooo much better than my professor.
Great!
Crazy I enrolled in school, and my teacher is linking videos of you teaching to supplement our curriculum. Thank you so so so much for what you do.

Comparing the one to many to users and comments made the concept much more relatable and understandable.
This illustrates one user many comments.

Marriage examples were great way to illustrate this
What is the best database relationship design for rent and gallery ? Is it the best design that each rent has multiple images(living room, kitchen, bathroom) and each image will be associated to only one rent ?

Hey Caleb ,
First of all, thanks a lot for teaching this stuff, I love it!
I have a question -
If I've got two entities,
And I want to connect their tables.
Let's say I have these two tables "husband" and a "wife"
Each husband can have only one wife, and each wife can have one husband
(A One to one connection)
How do I decide which one of them will hold the PK and which of them
will have the FK of the other?
If each of the tables will have a row of an entity with the FK of its pair,
won't that cause an integrity issue?(like if I update only the wife with the
new husband , but I forget to update it on the husband table ….)
Or should I use a look up table
to pair them together.
Sorry if you already explained that and I missed it .
Thanks a lot and keep up the good work, it's much appreciated J
nice vids
Thank you Caleb, you're an amazing teacher and you're super cute too
just perfect
Man, with that example, you have walked into a mine field. Good luck
Does "many to one relation exist"I?
If yes does "one to many" and "many to one" relation similar?
I think the names could be used to describe the same thing, just flipping the direction.
You realy need to get a white board
Dude, please how do I implement these
Use lucidchart
