Lots of DataData come from many quarters.

Social media sites

Sensors

Business transactions

Location-based

Dimensions of Big Data

Volume: large volumes of data

Velocity: quickly moving data

Variety: structure, unstructured, images, audios,

videos etc.

Why Big Data?

Business value outcomes tied to

the business strategy resulting

from business decisions.

Higher productivity, faster time

to complete tasks

Lower total cost of ownership

and greater efficiencies in IT

Big Data Technologies Operational

NoSQL

Analytical Hadoop

Problem in RDBMS Scalability Semi-structured and

unstructured Data.

High Velocity

Some concept NoSQL Schema less : data structure is not predefined

Focus on retrieval of data and appending new data

Focus on key-value data stores that can be used to locate data objects

Focus on supporting storage of large quantities of unstructured data

SQL is not used for storage or retrieval of data

No ACID (atomicity, consistency, isolation, durability)

MongoDB Built for cloud

Scale out architecture Agility afforded by cloud

computing Sharding automatically

distributes data evenly across multi-node clusters

Automatically manages redundant servers. (replica sets)

Horizontal scalality

Application
