Is NoSQL hard to learn?

In short, use NoSQL databases are not hard. The difficulty is using it in the right place in the right way.

Should I use SQL or NoSQL?

If your data is very structured and must comply with ACID, SQL is a good choice. On the other hand, if your data requirements are ambiguous or your data is unstructured, then NoSQL may be your best option. Data stored in NoSQL databases does not require a predefined schema like SQL databases.
