NoSQL has fewer users than relational databases – True

Say you have a thousand thermometers but only a few hundred users looking at them – this means you have many more writes than reads, making a NoSQL database ideal. On the flip side, let’s say you have a smaller number of writes, and many more reads, for example in a social media app where a popular person is posting something. It may be easier to support this on a relational database if you can divide your queries into read-only queries and write queries, where the writes can be handled by a single machine, allowing you to then scale reading without any limits and without losing ACID properties.

Regarding support, you’ll generally find that more help is available for SQL databases than for NoSQL. This is because SQL is a more established technology and thus has many more users and developers who can help you with your problems. In contrast, NoSQL is still relatively new, with less help available on forums or through the community.
