I really enjoyed this talk!
It started as an introduction of nosql databases and went into more detail. Of course Derick has a lot of experience in this area so any questions asked were answered directly with a good explanation.
Showing an ERD from a RDMS and how it evolves to use with MongoDB was really interesting. I think a talk just for that would be something I would be interested in. Or even a hands-on tutorial? ;)
Thanks again for sharing Derick :)
