MongoDB

Introduction :
MongoDB is a cross-platform, document-oriented database that provides high performance, high availability, and automatic scaling. It is a NoSQL database, which means that it does not use a fixed schema and does not rely on tables and rows to store data. Instead, MongoDB stores data in flexible, JSON-like documents, which can have any number of fields and can be nested. It also uses a dynamic schema, which allows for the addition, deletion, and modification of fields in a document without the need for fixed tables. MongoDB can be used for a wide range of applications, including big data, content management, and real-time analytics.

Why MongoDB ?
High performance: MongoDB is designed for high performance and can handle large amounts of data and high traffic. It uses a memory-mapped storage engine and an indexing system that allows for fast querying and data access.

Scalability: MongoDB is highly scalable and can automatically distribute data across multiple servers. This allows for horizontal scaling and easy management of large data sets.

Flexibility: MongoDB uses a document-oriented data model, which allows for flexible and unstructured data. This makes it easy to store and query data in a variety of formats, including nested objects and arrays.

High availability: MongoDB supports automatic failover and replication, which ensures high availability and disaster recovery.

Cross-platform: MongoDB runs on a variety of platforms, including Windows, Linux, and macOS. It also supports multiple programming languages, including Java, Python, and C#.

Rich query language: MongoDB has rich query language that supports ad-hoc queries, indexing, and real-time aggregation, which enables powerful ways to access and analyze the data

Cloud support: MongoDB has cloud-based solutions, like MongoDB Atlas, which allows you to easily deploy and manage MongoDB clusters in the cloud.

Community support: MongoDB has a large and active community, which provides support, tutorials, and resources for developers and administrators.
