MongoDB seems to be the go-to modern JSON-based database these days - it feels way faster and more flexible then MySQL ever was.
I was prompted to go for mongodb for the steemvids backend for a few reasons :
- Theres heaps of guides around to help learn the MEAN stack
- I found a few free mongodb providers to play with while I'm learning (eg: cloud.mongodb.com)
- It's what steemdata uses
