MongoDB is a NoSQL database designed for flexibility, scalability, and high performance.
Instead of storing data in traditional tables (like SQL databases), MongoDB stores data in JSON-like documents called BSON (Binary JSON).

🔹 Key Features of MongoDB:

Document-Oriented:

Data is stored in collections of documents.

Each document is a JSON-like structure (key-value pairs).

Schema-Less:

Documents in the same collection can have different fields.

Great flexibility in data modeling.

Scalability:

Built to handle horizontal scaling using sharding.

High Performance:

Optimized for read/write operations.

In-memory storage engine support.

Rich Query Language:

Support for CRUD operations, filtering, sorting, aggregation, etc.

Indexing:

Supports primary, secondary, and compound indexes for fast queries.

Aggregation Framework:

Powerful pipeline for transforming and analyzing data.

Replication:

Provides high availability through replica sets.
