What is MongoDB? List main features.

MongoDB is a popular NoSQL database designed for modern applications. Unlike traditional relational databases, MongoDB stores data in flexible, JSON-like documents rather than tables. This makes it ideal for handling unstructured or semi-structured data while offering scalability, high performance, and ease of use.

Main Features of MongoDB:
  1. 1

    Flexible Schema: Supports schema-less design, letting you adapt to changing requirements without rigid constraints.

  2. 2

    High Scalability: Horizontal scaling is achieved through sharding, where data is distributed across multiple servers.

  3. 3

    Replication: Provides redundancy and high availability through replica sets, ensuring data is consistently replicated across nodes.

  4. 4

    Indexing: Supports various index types to optimize query performance, including single field, compound, and text indexes

  5. 5

    Geospatial Queries: Enables queries for geolocation data, making it useful for applications requiring maps or location-based features.

  6. 6

    Rich Query Language: Includes powerful query capabilities, such as filtering, sorting, aggregations, and joins using the operator.
