You may wonder why NoSQL exists when a relational database is powerful enough to store data. As the internet grows, data grows exponentially. And data comes in different shapes and forms. For example, there is more and more long-form document data that needs to be stored somewhere. Not only do we need a database solution to store long-form document data, but it also allows us to query the text data efficiently. Relational databases aren't built for such a use case. Therefore, there are more and more new database technologies emerging, especially in the world of NoSQL databases.
