What is MongoDB?

MongoDB - one of the NOSQL database is document oriented database used to contain complex and high volume data in efficient manner. This database provides the scalability and flexibility that helps in querying and indexing the data from the documents of the database. Developers can easily learn and use the capabilities to meet the complex requirements at any scale. Being a NOSQL tool, data in database is not stored as usual rows and columns rather than data is stored in the form of key-value pairs. Schema of the database can be designed on the fly and modified without having any downtime.

Why use MongoDB?

1. MongoDB is one of the most commonly used database in this cloud computing scenario. Drivers for the 10 languages are available to embed the MongoDB with your project assignments. Much more features of MongoDB are available here that make it more compatible for the developers:
2. As MongoDB is object oriented database, so data is stored in flexible and JSON like documents. This allows the fields of the documents and data structure vary over time and makes it more usable for industries to store large amount of data.
3. MongoDB provides the user friendly document model, which maps the objects in the application code which makes the code much easier for the developers to create and maintain as well.
4. Ad-hoc Queries, range queries, regular expressions, indexing and real time aggressions provide the powerful ways to access the complete document as well as specific fields within the documents.
5. Replication feature of the MongoDB provides higher availability of the instance of the database. Each replica consists of one or more instance of the database.
6. Being a distributed database, MongoDB provides more accessibility, availability, horizontal scaling and geographic distribution of the database which makes it more easy to work with.
7. Load Balance is one of the most important feature of MongoDB, with the help of horizontal scaling, data is split into multiple instances of database which can be run on multiple servers.
8. MongoDB is free to use and free to extend as it is open source available for developers.
