Tell me about MongoDB MongoDB is a popular open-source document-oriented database management system. It falls under the category of NoSQL databases and is designed to handle large volumes of data with high performance and scalability. MongoDB uses a flexible, schema-less document model, which allows for dynamic and unstructured data storage. Some key features of MongoDB include: 1. Document-oriented: MongoDB stores data in flexible JSON-like documents, which can vary in structure and fields without requiring a predefined schema. 2. Scalable: It supports horizontal scaling by sharding, where data is distributed across multiple servers, allowing for easy scalability as the application grows. 3. High Performance: MongoDB provides fast read and write operations due to its memory-mapped storage engine and efficient indexing capabilities. 4. Replication and Fault Tolerance: It supports automatic replication, allowing data to be replicated across multiple servers for increased availability and fault tolerance. 5. Flexible Querying: MongoDB offers a powerful query language that supports complex queries, indexing, sorting, and aggregation operations on documents. 6. Rich Functionality: It provides various features like geospatial indexing, text search capabilities, real-time change streams, full-text search, etc., making it suitable for a wide range of applications. 7. Community Support: MongoDB has a large community of developers providing support through forums, user groups, documentation, and extensive online resources. MongoDB is commonly used in modern web applications, content management systems (CMS), real-time analytics systems, IoT applications, mobile apps, and other scenarios where flexibility and scalability are important. # References ```dataview Table title as Title, authors as Authors where contains(subject, "MongoDB") or contains(title, "MongoDB") ```
