Database ERD... and video marketing from Lucidchart

Accidentally bumped into some great video tutorials on database and ERD basics. And it's an ad from Lucidchart. Apparently a lot of people found these videos to be vastly helpful as well. That guy was explaining concepts really clearly with great examples. Sad there are only 3 of them. He should really market himself and sell courses on database management.

Then I continued to find all these amazing marketing videos from Lucidchart. They do a series on internet animal memes that are simply funny and addictive! Might not be high on conversions, but definitely makes viewers respect (and love) this company. It's so creative... I wouldn't have come up with something like this for a diagram software.
