MongoDB

MongoDB offers a flexible, document-oriented storage system perfect for modern application development. Data is stored in BSON documents, which can contain arrays and nested structures, closely aligning with object-oriented programming. This eliminates object-relational mapping overhead. The database supports ad-hoc queries, indexing, and real-time aggregation for powerful data access. Its horizontal scalability through sharding and replication ensures high availability and fault tolerance. Developers favor MongoDB for its ease of use in building applications that require adaptable data models and high performance.
