Is it worth it to study NoSQL?

Is NoSQL really needed?

It's time for us to admit what we have all known is true for a long time: NoSQL is the wrong tool for many of the modern application use cases, and it's time that we move on. NoSQL came into existence because the databases at the time couldn't handle the scale required.

Does NoSQL have a future?

It is clear that there is something happening in the database market and is hugely driven by the Big Data adoption. While other databases are not going to business anytime soon, there is a very bright future for NoSQL.

How hard is it to learn NoSQL?

In short, using NoSQL databases is not difficult. The difficulty comes in using it for the right places in the right way. First of all, it is important to understand that NoSQL doesn't follow the same principles as Relational Databases such as fixed schemas, normalization, support for expressive queries like SQL.

Should I learn SQL or NoSQL?

If your data is very structured and ACID compliance is a must, SQL is a great choice. On the other hand, if your data requirements aren't clear or if your data is unstructured, NoSQL may be your best bet. The data you store in a NoSQL database does not need a predefined schema like you do for a SQL database.
