NoSQL databases use javascript like the JOSN parameter to query! The basic operations are the same, but nested JOSN will produce complex queries.

Abstract: Although SQL database is a very useful tool, after 15 years of outstanding performance, the monopoly will be broken. This is only a matter of time: I was forced to use relational databases, but I finally found that I could not meet my needs. For details, see my IT-Homer blog: Comparison of eight mainstream NoSQL databases NoSQL is a brand new revolution
What is the comparison between nosql and relational databases?
Advantages:
1) Cost: nosql databases are simple and easy to deploy. They are basically open-source software and do not need to be purchased and used at the same cost as Oracle, which is cheaper than relational databases.
2) query speed: nosql databases

While SQL databases are insanely useful tools, their monopoly ~ 15 years is coming to an end. And it was just time: I can't even count the things that were forced into relational databases, but never really fitted them.
