What is MongoDB Database and How Does it Work
When you think of databases, you may think of traditional relational databases like MySQL or PostgreSQL, with rigid tables and structured data. However, MongoDB stands out from these conventional systems with its NoSQL approach.
It’s designed to handle large-scale, complex data in a flexible and scalable way, making it perfect for modern applications.
Working of MongoDB
Flexible Schema
Unlike relational databases, MongoDB doesn’t require a fixed schema. You can add fields or change your data structure without major disruptions.
BSON Format
MongoDB stores data in a format called BSON (Binary JSON). This allows it to efficiently store complex data types, including arrays and embedded documents.
Replication
MongoDB uses a replication mechanism to ensure data availability and fault tolerance, ensuring your data is safe and always accessible.
Sharding
For horizontal scalability, MongoDB can distribute data across multiple servers (or shards), ensuring that your application and database grow with it.
Indexing
MongoDB supports indexing on any field, speeding up queries and searches even with vast amounts of data.
