MongoDB

MongoDB is a non-relational, document-oriented database that enables scalable and high-performance application development. It stores data in BSON format, allowing flexible schemas where fields can vary across documents.

MongoDB supports ad hoc queries, field-level indexing, real-time analytics, and automatic failover through replica sets. Its architecture includes a primary node with multiple secondaries to ensure high availability and data redundancy. Load balancing and horizontal scaling are achieved via sharding, distributing data across clusters for efficient performance.

MongoDB is often used in content management systems, IoT, real-time analytics, and e-commerce platforms. Its open-source nature and support for multiple languages like Python, Node.js, and Java make it a developer favorite. MongoDB also offers managed cloud hosting through MongoDB Atlas and adheres to the SSPL license.
