NoSQL databases can contain a variety of data types and are not as structured as SQL databases. As a result, non-relational databases offer greater adaptability and flexibility, making them a better alternative for dealing with vast amounts of unstructured, unconnected data. In general, the larger the dataset, the more likely a NoSQL database is the preferable choice. Non-relational databases excel in scalability and availability, making them excellent for social networks and real-time applications (for example, online gaming and instant messaging).
