What is MongoDB?

MongoDB is a document-oriented, NoSQL database developed by 10gen in 2007. It is a hash-based, schema-less database that does not have a Data Definition Language. It allows storage of hashes with any keys and values, with keys being stored as strings and document identifiers (_id) created for each document. Signup and view all the answers

Study Notes

MongoDB Overview

MongoDB is a NoSQL database, specifically a document-oriented database.

Programming Languages Supported

MongoDB's APIs (drivers) support multiple programming languages, including:
- Java
- Python
- Ruby
- C++
- C#
- Node.js
- PHP
- Perl
- Scala
- Go

MongoDB Functionality

MongoDB offers a rich set of functionalities, including:
- Ad-hoc querying
- Indexing
- Aggregation
- Data replication
- Load balancing
- Capped collections
- Embedded data models

Data Storage

MongoDB stores data in a JSON-like format called BSON (Binary Serialized Object Notation).

Replication

MongoDB supports master-slave replication, which allows for automatic failover and redundancy.

Comparison with Other NoSQL Databases

In DynamoDB and Azure Table Storage, key-value pairs are used to store data.
In contrast, MongoDB uses a document-oriented data model.

Why Use MongoDB?

MongoDB is a popular choice for modern applications due to its:
- Scalability
- Flexibility
- High performance
- Ease of use
- Rich ecosystem of tools and drivers
