I have previously worked with Relational databases and they are pretty much very easy to implement.
Recently I got curious about Nosql databases.
But I have no idea how I should get started with ?
I as far as I have researched there are 4 types of nosql databases i.e Key-value , Column based , Graph based & Document based ..., Now I am confused how should I go about learning them ?
Since mostly I would be using Relational databases , & Nosql would rarely come up , but I was wondering to have an surface level knowledge of at least the 4 types of nosql databases.
Can you please recommend me something?
What I have tried:
tried looking online and some papers
