MongoDB Features

What is MongoDB?
MongoDB could also be a document-oriented NoSQL database used for top volume data storage. Instead of using tables and rows as within the normal relational databases, MongoDB makes use of collections and documents. Documents contain key-value pairs which are the essential unit of data in MongoDB. Collections contain sets of documents and performance which is that the equivalent of on-line database tables. MongoDB could also be a database which came into light around the mid-2000s.

MongoDB Features
1. Each database contains collections which successively contains documents. Each document is often different with a varying number of fields. The size and content of each document are often different from each other.
2. The document structure is more in line with how developers construct their classes and objects in their respective programming languages. Developers will often say that their classes aren't rows and columns but have a transparent structure with key-value pairs.
3. The row (or documents as called in MongoDB) doesn’t need to have a schema defined beforehand. Instead, the fields are often created on the fly.
4. The data model available within MongoDB allows you to represent hierarchical relationships, to store arrays, and other more complex structures more easily.
5. Scalability – The MongoDB environments are very scalable. Companies across the earth have defined clusters with variety of them running 100+ nodes with around many documents within the database
