What is MongoDB ?

MongoDB is a popular open-source, NoSQL database management system designed to store and manage large volumes of unstructured or semi-structured data. It employs a document-based model, where data is stored in JSON-like BSON format, allowing flexibility and scalability for complex data structures. MongoDB's key features include horizontal scaling, automatic sharding, and support for geospatial indexes. It enables developers to build modern, scalable applications with ease, making it a go-to choice for various use cases like web applications, mobile apps, and IoT applications. MongoDB's dynamic schema and powerful querying capabilities make it well-suited for agile and evolving data requirements.
