What is mongo db?

MongoDb document based no-sql database. To query mongodb we use json.

Benefits:

i) Programmers only need to create a data model that fits there application.

ii) mongodb predicates on data models to it is easy to shard data or distribute data on multiple servers.

iii) Supports scaling out feature.

iv) We dont need to depend on deployment model.it can deployed easily on one server or one node,a few nodes or a hundred of shards.

v) In MongoDB, a write operation is atomic on the level of a single document, even if the operation modifies multiple embedded documents within a single document.When a single write operation modifies multiple documents, the modification of each document is atomic, but the operation as a whole is not atomic and other operations may interleave.
