The beauty of the emergence of technologies such as MongoDB is that they allow us to store data in a more natural form. Before they became relevant, engineering teams were always faced with the daunting task of shoe-horning in all types of data into the relational model.
Unlike traditional RDBMSs, NoSQL databases often trade how ACID (atomic, consistent, isolated, and durable) transactions are for improved performance.
NoSQL solutions are great for large data sets with high volumes of writes that need to be distributed over wide geography (multiple regions or data centers), where there is some tolerance for marginal loss of data in the event of a disaster recovery scenario.
In summary, when people claim that the above is a replacement for relational databases, that's only partially true. With these technologies, we can now push off forms that don't fit well with the relational model into more natural storage mechanisms based on our needs for access, response time, cost, and growth.
