Are relational databases obsolete?
Relational Database Management Systems (RDBMS) and Structured Query Language (SQL) associated with them represent a mature technology that existed for over 30 years.

Does anyone use SQL anymore?
For businesses, the quick answer is yes. Even with tableless databases such as MongoDB and Firebase becoming mainstream, and being advocated for by developers as well as being used in increasing proportion, SQL is still relevant — especially from data persistence and scalable cost perspectives.
Is NoSQL the future?
Today, we have around 300 exabytes of unstructured data and it is increasing by the day. The predicted rise of unstructured data is at 56\% per annum, compared to 12\% for the structured data; this is why “NoSQL database” is believed to be the database of the future.
