Using MongoDB in Linux

Using MongoDB in Linux
 MongoDB is free, open-source Database software. MongoDB (from humongous) is a cross-platform document-oriented database. Classified as a NoSQL database, MongoDB eschews the traditional table-based relational database structure in favor of JSON-like documents with dynamic schemas (MongoDB calls the format BSON), making the integration of data in certain types of applications easier and faster.

Use can use MongoDB when.....................

Expect a High Write Load
Need High Availability in an Unreliable Environment (Cloud and Real Life)
Need to Grow Big (and Shard Your Data)
Data is Location Based
Data Set is Going to be Big (starting from 1GB) and Schema is Not Stable
Don't have a DBA

yum install mongodb-server
yum install java
