NoSQL Database

NoSQL databases are non-relational data management systems designed for handling large volumes of unstructured or semi-structured data, offering high scalability and flexibility. They use various data models such as document, key-value, column-family, and graph, and are optimized for distributed architectures and real-time web applications.

Also known as: Not Only SQL, Non-relational database, NoSQL DB, No-SQL, NoSQL datastore

Why learn NoSQL Database?

Developers should use NoSQL databases when building applications that require horizontal scaling, low-latency access, or flexible schema designs, such as big data analytics, content management systems, or IoT platforms. They are particularly valuable for handling diverse data types and high-velocity data streams where traditional SQL databases might struggle with performance or rigidity.
