What is MongoDB?

MongoDB is a cross-platform, open-source database that uses a document-oriented data model, rather than a traditional table-based relational database structure. This type of model makes the integration of structured and unstructured data easier and faster.
How does MongoDB work?
MongoDB is a NoSQL database that stores large amounts of data using JSON-like documents along with optional schemas. Its flexible data storage model not only makes querying easier for the user, but it makes database management easier for developers.
