MongoDB is scalable, flexible and an open-source NoSQL Database that was founded in 2007. It has shown a lot of potential in managing user data and creation of centralized databases. Since MongoDB is a schema-less database, it becomes very easy to scale while adding functionality to the applications being developed. It has load balancing capability and horizontal scaling provides unprecedented level of scalability and flexibility. 

Why MongoDB?

• Easy to install, operate, and scale with a flexible schema
• Ease of manipulating data, creating/deleting tables and querying to MongoDB without an intensive learning curve
• Ease of configuration and lightweight compared to other databases
• Meets project requirements very well and stores the data taking minimum disk space when compared to any other RDBMS
• Allows for performing joint operations on different collections despite being a NoSQL database, and allows performing various other operations while doing joint operations
• Replica sets: Replica sets has always kept data consistent and reliable in case of database failures. This is especially when dealing with heavy databases to work with real-time data
• Create and manage the MongoDB database either on your local machine using Mongo Bash or store it in the cloud using MongoDB Atlas
• Allows the export of non-relational databases
• Easy integration with JS code
