MongoDB is a general-purpose NoSQL document-oriented database designed for modern applications. Created for working with unstructured data, it’s used by Facebook, Google, Verizon, PayPal, Intuit, and many others.
MongoDB is a distributed database with high availability, horizontal scaling, and geographic distribution. It also provides support for ad hoc queries and indexing for easy access and analysis of data.
You can use MongoDB at no cost, however, managed services such as Atlas or AWS DocumentDB offer premium cloud services.
There is a wide selection of computing systems that use MongoDB, such as those on-premise and those in the cloud. Besides its common application, it is also employed in custom database development for configuration management, emerging data requirements, E-commerce product catalogs, and social networking sites.
Implementing suitable indexes to improve performance, refining backup and recovery processes, and following the best practices when integrating REST APIs into a framework or model are all part of a MongoDB developer's job.
MongoDB uses its own query language, called the MongoDB Query Language (MQL). The structure of MQL is not the same as SQL, which is regularly used for database tasks. The MongoDB documentation provides a comparison of the two query languages.
