What is MongoDB? Nedir?
MongoDB is a document-oriented NoSQL database that works with flexible JSON-like data structures.
MongoDB was developed by MongoDB Inc. (formerly 10gen) in 2009. As an alternative to the rigid schema structure of relational databases, it's a NoSQL database that works with flexible BSON (Binary JSON) documents. MongoDB's schemaless structure allows data of different structures to be stored in the same collection. This flexibility is ideal for rapid prototyping and applications with constantly changing data models. Aggregation pipeline, rich query language, full-text search, and geospatial indexes provide powerful data processing capabilities. MongoDB Atlas is a fully managed cloud database service running on AWS, Azure, and Google Cloud. Replica sets provide high availability, and sharding enables horizontal scalability. Change Streams allow real-time data flow monitoring. Major companies like eBay, Adobe, SAP, Verizon, and Electronic Arts use MongoDB. The MEAN/MERN (MongoDB, Express, Angular/React, Node.js) stack is a popular combination in web development.
