It offers the power of relational databases by supporting full ACID transactions, joins in queries, and two types of relationships instead of one: reference and embedded.It comes with a rich and powerful query language (to support read and write operations), supports data aggregation, and other modern use-cases such as text search, graph search, and Geospatial queries.Besides, its indexes allow for faster queries and importantly, they can include keys from embedded documents and arrays. It supports embedded data models that alleviate I/O activity on the database system. MongoDB is designed for high performance and data persistence.Besides, it supports multiple storage engines and provides a pluggable storage engine API that you can use to develop your storage engines. It also supports arrays and nested objects as values allow for flexible and dynamic schemas. MongoDB supports read-only views and on-demand materialized views.The following are the key features of MongoDB. A record in MongoDB is a document (a data structure composed of field and value pairs, similar to JSON objects) and documents are stored in collections (analogous to tables in RDBMS). The server must be running for clients to connect and interact with databases.ĭata storage under MongoDB is different from traditional databases. MongoDB is structured on a client-server model where a server daemon accepts connections from clients and processes database actions from them. MongoDB is offered in two different editions: MongoDB Community Server which is the source-available and free-to-use edition of MongoDB and MongoDB Enterprise Server that is a part of the MongoDB Enterprise Advanced subscription.
It comes with a comprehensive suite of tools for easy data management and it is built for modern application development and for the cloud and intended for use by developers, data analysts, and data scientists. MongoDB runs on Linux, Windows, and macOS operating systems. It is a powerful and flexible, agile NoSQL (non-relational) document database that stores data in documents similar to JSON ( JavaScript Object Notation) objects.
MongoDB is an open-source, modern, general-purpose, document-based distributed database management system developed, distributed, and supported by MongoDB Inc.
