Merriman & Horowitz helped kind 10GenInc. in 2007 to commercialize MongoDB and its connected software's. the corporate was renamed to MongoDB Iraqi National Congress. in 2013.

This info may be a document info with flexibility and measurability needed for all the querying and classification. rather than victimization tables and rows that is that the case in relative databases, MongoDB is built on the design of collections and documents. These documents comprise of sets of key worth pairs and function the fundamental unit knowledge in MongoDB. On the opposite hand, assortment contains sets of documents and functions as the equivalent of electronic information service tables.

MongoDB supports dynamic schema style similar to NoSQL databases, that permits the documents in a very assortment having completely different fields and structures.

The Mongolian monetary unit info was discharged to open supply within the year 2009 and is accessible underneath the terms of the free code foundation wildebeest AGPL Version three.0 industrial license.

Features of this info are:

Indexing: Fields during this info document is indexed with primary and secondary indices.
Replication: MongoDB Contributes high accessibility with reproduction sets. a duplicate set includes 2 or a lot of copies of information.
Load Balancing: MongoDB scales horizontally victimization sharding. It will run on multiple servers that help to balance the load and conjointly duplicating the information for keeping the system up and running just in case of hardware failure.
File storage: It is used as a classification system which incorporates load reconciliation and knowledge replication options over multiple machines for storing files.
Aggregation: The framework allows the user to get the sort of results that the SQL cluster by clause is employed.
Server - facet JavaScript Execution: JavaScript is employed in queries, combination functions (such as Map Reduce), and conjointly directly sent to the info to be dead.
Capped Collections: MongoDB supports mounted size collections known as capped collections.
The main purpose that MongoDB is built:
Improve measurability
Improve Performance
High accessibility
Scaling switched from single server deployments to complicated and huge multi-site architectures.
