Explaining the case for MySQL
My faithful readers, please spare 10 mins of your time, and read Baron's excellent post: https://vividcortex.com/blog/2014/04/30/why-mysql Nuff said. Since I can't really shut up, and only if you do like my (humble) take on this, I could say in short: Every...

Is it really?

"If there were cloud-oriented SQL databases that could do the kind of elastic scalability that was needed, handle then volumes of data that were required, then there never would have been a requirement for NoSQL"
Summary: If there was a NoSQL storm brewing earlier this decade, Hummer Winblad’s Mitchell Kertzman thinks it has all but died down. People thought NoSQL would blow up the SQL world, he said on this week’s Structure Show, but it might just be a nice complement.
