INTRODUCTION :-* “BIG DATA” IS A TERM THAT DESCRIBES THE LARGE VOLUME OF

DATA – BOTH STRUCTURED AND UNSTRUCTURED.* “BIG DATA” BURST UPON THE SCENE IN THE FIRST DECADE OF

THE 21ST CENTURY.* THE FIRST ORGANIZATIONS TO EMBRACE IT WERE ONLINE AND

STARTUP FIRMS. FIRMS LIKE GOOGLE, EBAY, LINKEDIN, AND FACEBOOK WERE BUILT AROUND BIG DATA FROM THE BEGINNING.

WHAT IS BIG DATA?

* “BIG DATA” IS SIMILAR TO ‘SMALL DATA’, BUT BIGGER IN SIZE.* “BIG DATA” IS DATA WHOSE SCALE, DIVERSITY, AND

COMPLEXITY REQUIRE NEW ARCHITECTURE, TECHNIQUES, ALGORITHMS, AND ANALYTICS TO MANAGE IT AND EXTRACT VALUE AND HIDDEN KNOWLEDGE FROM IT…

CHARACTERISTIC OF BIG DATA:-

THERE ARE THREE CHARACTERISTIC OF BIG DATA:1) VOLUME ( SCALE )2) VELOCITY ( SPEED )3) VARIETY ( COMPLEXITY )

WHY BIG DATA:- FB GENERATES 10TB DAILY TWITTER GENERATES 7TB OF DATA DAILY IBM CLAIMS 90% OF TODAY’S STORED DATA WAS GENERATED IN JUST THE LAST

TWO YEARS. FOR THOSE REASON WE NEED BIG DATA.

BIG DATA SOURCES:-

OUR PROGRESS AND INNOVATION ARE INCREASED DAY TO DAY BUT IN BACK END THEIR HAVE LOTS OF DATA.

Social media and networks(all of us are generating data)

Scientific instruments(collecting all sorts of data)

Mobile devices (tracking all objects all the time)

Sensor technology and networks

(measuring all kinds of data)

TOOLS USED IN BIG DATA:-

APACHE HADOOPMICROSOFT HDINSIGHTNoSQLHIVESQOOPPOLYBASEPRESTO

APPLICATION OF BIG DATA:-F

FUTURE OF BIG DATA: $15 BILLION ON SOFTWARE FIRMS ONLY SPECIALIZING IN

DATA MANAGEMENT AND ANALYTICS. THE MCKINSEY GLOBAL INSTITUTE ESTIMATES THAT DATA

VOLUME IS GROWING 40% PER YEAR, AND WILL GROW 44X BETWEEN 2009 AND 2020.
