BIG DATAAn Introduction

DATA

What is Data?Information in raw or unorganized form (such as alphabets, numbers,

or symbols) that refer to, or represent, conditions, ideas, or objects.

Distinct pieces of information, usually formatted in a special way.

A collection of facts, such as values or measurements.

Data can exist in a variety of forms -- as numbers or text on pieces of

paper, as bits and bytes stored in electronic memory, or as facts

stored in a person's mind.

Few ExamplesA word file, an excel sheet, an image, an e-mail, a Facebook status, a

Twitter tweet, a YouTube video and the list is endless.

EVOLUTION OF COMPUTERS

1960 Main Frame Computers Took large space. Occupied an entire room.

All data centralized. Stored at a single location.

To analyze the data stored, physicists had to come from across the globe.

No networks. Difficult management of data.

1970 IBM Clones Comparatively less space. Occupies an entire rack.

De-centralization of data starts.

Mainframes moduled into small units, data distributed across them.

Modules connected with network bridges.

Computers become feasible.

1980-90 Desktop Computers Get arranged simply on a desk.

Internet expands and becomes global, network protocols developed. Ease of

data communication and sharing. Access from remote locations.

Amount of data increases in many folds. Still in use widely in offices, institutes etc.

Late 90s-2000 Laptop Computers Computers become portable and handy-mobile. Commonly used in a variety of settings, including work,

education, and personal multimedia.

A laptop combines the components and inputs as a desktop

computer; including display, speakers, keyboard, and pointing device.

Modern day laptops are equipped with connecting and networking

technologies such as Bluetooth, WI-FI etc.

In wide use across the globe.

2010 Tablet Computers A tablet computer, or simply tablet, is a mobile computer with display,

circuitry and battery in a single unit. Tablets are equipped with sensors, including cameras,

microphone, accelerometer and touch screen, with finger or stylus

gestures replacing computer mouse and keyboard.

Used widely for networking purposes.

THE INTERNET

Technologists say, the world has turned to a Global Village. Well, the credit

to this goes to the Internet.

The Internet has made distances shorter and the world smaller.

In a matter of very few years, the Internet consolidated itself as a verypowerful platform that has changed forever the way we do business,

and the way we communicate.

Size of InternetExpanding Daily. Every hour, every minute, rather every

second.

The Internet is defined as the worldwide interconnection of individual

networks operated by government, industry, academia, and private parties.

THE PROBLEMThe core problem going by todays scenario is the extensively

growing quantum of Data.

The world's technological per-capita capacity to storeinformation has roughly doubled every 40 months since the 1980s.

From the beginning of human history till 2003 only 5 exabytes of

data was generated. But since then, the situation has transformed

drastically.Everyday we create 2.5 quintillion bytes of data; 90% of the data

in the world today has been created in the last two years alone.

1 Quintillion = 10^18 bytes i.e 1000000000000000000 bytes or 1

exabyte. Too much.. Right?

Predictions say that the same amount of data would be generatedin minutes in the days to come.

The Big Question How to manage & process this enormous data

store using the present technologies?

THE PROBLEM

Few Illustrations How Much Data?

Google processes 20 PB a day

Wayback Machine has 3 PB + 100 TB/month

Facebook has 2.5 PB of user data + 15 TB/day

eBay has 6.5 PB of user data + 50 TB/day

CERNs Large Hydron Collider (LHC) generates 15 PB a year

Social media and networks

(all of us are generating data)

Mobile devices

(tracking all objects all the time)

Sensor technology and

networks(measuring all kinds of data)

BIG DATA A SOLUTION?

What is Big Data?

It is an elusive concept.

Represents the collection of digital data that is uncomfortable to store, transport

and analyze.

Big datais the term for a collection of data sets so large and complex that it

becomes difficult to process using on-hand database management tools ortraditional data processing applications. The challenges include capture,

curation, storage,search, sharing, transfer, analysis,and visualization.

Challenges us to create next-gen data storage tools and techniques.

Old concept- Few companies generate data, all others consume it.New concept- All of us are generating data, and all of us are

consuming the same.

Big Data usually includes data sets with sizes beyond the ability of

commonly used software tools to capture, curate, manage, and process the

data within a tolerable elapsed time.
