MongoDB is a popular NoSQL database management system that stores, retrieves, and manipulates data. It is particularly well-suited for handling large volumes of unstructured data and is often used in big data and cloud computing applications.
MongoDB works on the concept of documents and collections, making data storage incredibly flexible, scalable, and efficient. MongoDB also provides many features such as high availability, horizontal scalability, rich query language and robust security features which makes it suitable for all types of applications that are serving large amounts of data at any time.
Using MongoDB, you can store application data in just one unified format regardless of its structure while running complex queries to quickly pull out any required information.
