MongoDB 6 on Ubuntu 23.04 LTS is a flexible, scalable NoSQL database designed for handling large volumes of unstructured or semi-structured data. Unlike relational databases, it stores data in JSON-like documents, making it easier to adapt to changing requirements. MongoDB is widely used in applications such as e-commerce, social networks, and big data analytics. Its powerful query capabilities and indexing features enable fast data retrieval. The database supports high availability through replication and offers horizontal scalability with sharding. MongoDB is ideal for modern web and mobile applications requiring flexibility and high performance.
