WHAT IS NOSQL?
All Databases
Relational Databases (Oracle, mySQL,
Postgres, SQL Server)
NoSQL(MongoDB, Redis, Neo4J, Cassandra,
Hbase)
No schema enforcedOpen source
Designed to run on large clusters
Not using the relational model
Model not using the SQL
language)
What is NoSQL?Martin Fowler: Some characteristics are common amongst these databases, but none are definitional.

WHAT IS MONGODB?
Open source NoSQL
database
Document-oriented
Stores JSON-like documents
(dynamic schemas)
Includes a strong query
language (Javascript)
Powerful, flexible
indexing (including
geospatial)
Sharding and replication
Cross-Platform (many drivers – e.g. C#, Java, Python, Ruby)

MONGODB - JSON & BSON
JSON Number String Boolean Array Object null
BSON = JSON + ObjectId DateTime Byte Arrays GeoSpatial
