No SQL Databases

If you ask me, I tend to think No SQL is a lot of hype – no relational databases as they are called are old as computing and data structures, and are the kind of thing you learn about in an elementary data structures class in college where they teach you about things like C structs and pointers. Key value stores aka hash tables are basic components   of most modern programming languages like Python, R and C++.

It’s not to say that the don’t have a roll – indeed many implementations of such data structures are much faster, secure and efficient than any one person could construct with a few lines of C code. But revolutionary? Worth the hype? No. No SQL isn’t going to replace SQL and relational databases anytime soon.
