Understanding MongoDB:
What is MongoDB?
MongoDB is a widely adopted, document-oriented NoSQL database known for its flexibility and scalability. It stores data in BSON (binary JSON) format, allowing for rich data structures and dynamic schemas. MongoDB is commonly used for various applications, including content management systems and real-time analytics.
Key Features of MongoDB:
- Document-Oriented: Stores data in flexible, JSON-like BSON documents.
- Rich Query Language: Supports dynamic queries and indexing, enabling complex data retrieval.
- Horizontal Scalability: Can scale horizontally across distributed clusters to handle increasing data loads.
