FOR INSTRUCTORS WHO ARE DOING ONLINE CLASSES: If there are other videos you need made please post a comment here. I will do what I can to help online education, especially during this time of challenges around the world. No charge (and no promises, so there is that). But I will do what I can.

Best, simplest, easiest to understand relational database and relationships in a nutshell.
No other videos come close to this one.
Please don't ever take this video down.

Thank you for this video. As someone who learns well visually, I think this visualizes the concept clearly for beginners.

I keep wondering why people are asking about composite keys and primary keys. This is a GREAT beginning overview of relational databases and how they work. Unique identifiers pretty much covers those questions.

Thank you so much for this video. I have been trying to understand how relational databases work and out of all the places I checked this is the only one that started at the beginning and didn't assume I was a computer expert. Thank you so much.

[neojabin]

Yo, this was awesome. I'm studying Django with my dad and in the course we're studying there are Relational database concepts, I didn't know them that well, thank you for the help

[DanielFassa]

Thank you SO GOD DAMN MUCH friend. I was starting to play with PowerPivot and Table Relationships in Excel and was struggling to get a hold of this concept as I was trying to connect 2 table directly without considering that the new relationship itself would be the hosted by a whole new table! Many many thanks!!
