It is an open source, cross-platform, and document-oriented database, which is defined as NoSQL database. You will not find the traditional table-based relational database structure instead there is JSON like documents with the dynamic schemas. This platform is developed by MongoDB Inc.
The main features of MongoDB are as follows:
Allows indexing of any field, including within arrays and embedded documents.
Provides higher availability with replica sets, comprising two or more copies of data. Each set of replica serves to be a primary or a secondary replica at any time.
Scales data horizontally through sharding, allowing the user to use the shard key to determine the data collection.
Offers the capability of being used as a file system by adopting the advantage of load balancing and replication of data over various machines to store files.
Provides support for fixed-size collections known as capped collections. Such collections manage insertion order and after the mentioned size is attained, it acts like a circular queue.
Following are the certain situations in which MongoDB is an ideal platform:
When you expect a high write load. In other words, if you need to load tons of data lines with a low business value for each one.
When you need high availability in an unreliable environment.
When you need to grow big and shard the data. In other words, if you need to partition and shard your database.
When your data is going to be big and schema is not stable.
HISTORY OF MongoDB
The software company 10Gen started the development of MongoDB in 2007, and in 2009 the company was shifted to an open source development model. The company was offering support for various services, and in 2013 the name of the company was changed from 10gen to MongoDB.
