The database refers to the document-oriented data model. Unlike relational types, MongoDB does not require tables, schemas, or a separate query language. All information is stored as documents or collections in a JSON-like format. MongoDB is characterized by high availability, scalability and security. The database is used not only in web programming, e-commerce and mobile applications. It is used for record information from monitoring sensors at manufacturing plants and storing events in the system. Quite often, MongoDB is used as a repository in machine learning and artificial intelligence.
