The internet has grown tremendously in the last decade, from 304 million users in March 2000 to 2280 million users in March 2012 according to internet worlds stats. Worldwide information is more than doubling every two years , with 1.8 zettabytes or 1.8 trillion gigabytes projected to be created and replicated in 2011 according to the study conducted by research firm IDC.

A buzzword,or catch –  phrase, used to describe a massive volume of both structured and unstructured data that is so large that is difficult to process with traditional database and software techniques is “Big Data”. An example of big data might be  perabytes(1,024 terabytes) or exabytes (1,024 petabytes) and zettabytes of data

consisting of billions to trillions of records of million of people

All from different sources (e.g blogs,social media,email,sensors,RFID readers ,  photographs,videos, microphones,mobile data and so on). The data is typically loosely structured data that is often incomplete and inaccessible. When dealing with larger datasets, organizations face difficulties in being able to create, manipulate , and manage Big Data. Scientists regularly encounter this problem in meteorology, Genomics, connectomics, complex physics simulations ,biological and environmental research, internet search , finance and business informatics. Big data is particularly a  problem in business analytics because standard tools and procedures are not designed to search and analyze massive datasets. While the term may seem to reference the volume of data , that isn‟t always the case. The term Big data, especially when used


 by vendors, refer to the technology(the tools and processes) that an organization requires to handle the large amounts of data and storage facilities.

Over a distributed storage system

Hadoop used to process unstructured and semistructured big data uses the map  paradigm to locate all relevant data then select only the data directly answering the query.NoSQL,MongoDB and TerraStore process structured big data. Nosql data is characterized by being basically available,soft state (changeable), and eventually consistent .MongoDB and Terrastore are both no sql-related products used for document –  orient applications .The advent of the age of big data poses opportunities and challenges for businesses.Previously unavailable forms of data can now  besavved,retrieved and processed . However, change to hardware ,software , and data  processing techniques are necessary to employ this new paradigm.

1.1 What is big data ?

Big data is a popular term used to describe the exponential growth and availability of data, both structured and unstructured. And big data may be as important to business –  and society –  as the Internet has become. Why? More data may lead to more accurate analysis. More accurate analysis may lead to more confident decision making. And  better decisions can mean greater operational efficiencies, cost reductions and reduced

1.2 The Importance of Big Data and What You Can Accomplish

The real issue is not that you are acquiring large amounts of data. It's what you do with the data that counts. The hopeful vision is that organizations will be able to take data from any source, harness relevant data and analyze it to find answers that enable 1) cost reductions, 2) time reductions, 3) new product development and optimized offerings, and 4) smarter business decision making. For instance, by combining big data and high-powered analytics, it is possible to:

1.4 Why big data is important it is shown in diagram?

For .e.g if you see in IBM BIG insight having a log analysis for performance

optimizer. Log is a volume,it can be formed in semistructure or row format. When there is a up gradation in any organization for e.g we can say upgrading the operating system or database or migration that time log also change the format sometimes.

We having another example why big data is important for e.g we can say any public sector and private sector bank having big data when customer come to the bank ,or customer having daily transaction in debit card and credit card . when transaction goes on log file has been generated . In online transaction each day log file having more than 5 terabytes. It is day to day log generated .we cant do delete logfile because it is more useful in organization.

1.5 Big data steps, vendors and technology landscape 1. Data Acquisition

Data is collected from the data sources and distributed across multiple nodes –  often a grid –  each of which processes a subset of data in parallel.

Here we have technological provier like IBM ,HP etc and data providers like reuters, saleforce etc and social network websites like facebook,google +,LinkedIn etc..


In This domain , we have very large data warehousing and BI appliances,actors like action ,emc2(greenplum),hp(vertica),IBM (netezza) etc.

3. Analytics

In this phase ,we have the predictive technologies (suach as data mining )and vendors which are adobe ,emc2,good data ,hadoop map reduce etc..

4. Action

Includes all the data acquisition providers plus the ERP ,CRM, and BPM actors including adobe,eloqua ,emc2 etc.both in analytical and action phases , BI tools vendors are good data ,google, hp (autonomy),IBM (cognos suite)etc.

5. Data Governance

An efficient master data management solution. As defined ,data governance applies to each of the six preceding stages of big data dlivery.By establishing process and guiding principles it sanctions behaviors around data delivery.By establishing  processes and guiding principles it sanctions behaviours around data. In short data governance means that the application of big data is useful and relevant. Its an insurance policy that the right questions are being we won‟t be squandering the immense powe of new big data technologies that make processing storage and delivery speed more cost effective and nimble than ever.

1.6 Operational Definitions 1.6.1 Data Scientist

A data scientist represents an evolution from the business or data analyst role. Data scientists also known as data analysts –   are professionals with core statistics or mathematics background coupled with good knowledge in analytics and data software tools. AMckinsey study on big data states indiawil need nearly ,100,000 data


scientists in the next few years.”A data Scientists is a fairly new role defined by Hillary mason of big as someone who can obtain ,srub, explore,model and interpret data, blending hacking, statistics and machine learning who culls information from data. These data scientists take a blend of the hackers arts, statistics and machine learning and apply their expertise in mathematics and understanding the domain of the data –   where the data originated –   to process the data into useful information . This require the ability to make creative ecisions about the data and the information created and maintaining a perspective that goes beyond ordinary scientific boundaries.

1.6.2 Massive Parallel Processing (MPP)

Mpp is the coordinated processing of a program by multiple processors that work on different parts of the program, with each processor using its own operating system and memory. An MPP system is considered better than a symmetrically parallel system(SMP) for applications that allow a number of databases to be searched in  parallel. These include decision support system and data warehouse applications.

1.6.3 In memory analytics

The key difference between conventional BI tools and in memory products is that the former query data on disk while the latter query data in random access memory(RAM).When a user runs a query against a typical data warehouse, the query normally goes to a database that reads the information from multiple tables stored on a server‟s shared Itdisk. With a serverbased inmemory database,all information is initially loaded into memory. Users than query and interact with the data load into the machine‟s memory.


1.6.4 Redundant Array of Independent Disk (RAID)

RAID is short for redundant array of independent (or inexpensive) disks.It is a category of disk drives that employ two or more drives in combination for fault tolerance and performance. RAID disk drives are used frequently on servers but aren't generally necessary for  personal computers. RAID allows you to store the same data redundantly (in multiple paces) in a balanced way to improve overall storage  performance

Does an memory analytics platform replace or augment traditional in-database approaches?

The answer is that it is quite complementary. In –  database approaches put a large focus on the data preparation and scoring portions of the analytic process. The value of in-database processing is the ability to handle terabytes or petabytes of data effectively. Much of the processing may not be highly sophisticated but it is a

critical.The new in memory architiectures use a massively parallel platform to enable the mutilpe terabytes of system memory to be utilized (conceptually) as one big pool of memory. This means that samples can be much larger, or even eliminated. The number of variables tested can be expanded immensely.


In –  Memory approaches fit best in situations where there is a need for:

1. High Volume & speed: it is necessary to run many,many models quickly

2. High Width &Depth : It is desired to test hundred or thousands of metrics across tens of millions customers.

3. High complexity : It is critical to run processing-intensive algorithms on all this data and to allow for many iterations to occur.


1. In Memory OLAP :- Classic MOLAP (multidimensional online analytical  processing ) cube loaded entirely in memory.

2. In Memory ROLAP : Relational OLAP metadata loaded entirely in memory. 3. In Memory inverted index :- Index with data loaded inot memory.

4. In Memory associative index : An Array / index with every entity / attribute correlated to every entity/attribute.

5. In-memory spreadsheet :- Spreadsheet like array loaded entirely into memory.

1.6.6 Structured , Semi – Structured and unstructured Data

Structured Data is that type that would fit nearly into a standard relational database management system,RDBMS, and lend itself to that type of processing.

Semi-Structured Data is the which has some level of commonality but does not fit the structured data type

Unstructured Datais the type that varies in it content and can change from entry to entry.

2.0 Big Data Infrastructure 2.1.1 Why RAID Fails at Scale

RAID schemes are based on parity and at its root, if more than two drives fail simultaneously , data is not recoverable . The Statistical likelihood of multiple drive failures has not been an issue in the past. However as drive capacities continue to grow beyond the terabyte range and storage systems continues to grow to hundreds of terabytes and petabytes, the likelihood of multiple drive failures is not reality.

Further drives aren‟t perfect and typical SATA drives have a published bit rate error(BRE) of 10 14, meaning100, 000,000,000,000 bits there will be a bit that is unrecoverable.Doesn‟t seem signigicant ? In Today bid data storage systems it is the likelihood of having one drive fail, and encountering a bit rate error when rebuilding from the remaining RAID set is highly probable in real world scenarios. To put this inot perspective, when reading 10 terabytes , the probability of an unreadable bit is likely (565%) and when reading 100 terabytes it is nearly certain (99.97%).

2.1.2 Scale up VS Scale out NAS

Traditional scale up system would provide a small number of access points, or data servers that would sit in front of a set of disk protected with RAID . As these systems needed to provide more data to more users the storage administrator would add more disks to the back end but this only caused to create the data servers as a choke point. Larger and faster data servers could be created using faster processor and more memory but this architecture still had significant scalability issues.Scale out uses the


approach of more of everything instead of adding drives behind aair of servers, it adds servers each with processor, memory,network interfaces and storageCapacity. As I need to add capacity to a grid –  to scale out version of an array –  I insert a new node with all the available resources. This architecture required a number of things to make it work from both a technology and financial aspect.

Some of these factors include. 1. Clusterd architecture

FOR this model to work the entire grid needed to work as a single entity and each node in the grid would need to be able to pick up a portion of the function of any other node that may fail.

2. Distributed / parallel file system

The file system must allow for a file to be accessed from any one or any number of nodes to be sent to the requesting system. This required different mechanism

underlying the file system : distribution of data across multiple nodes for redundancy , as distributed metadata o locking mechanism and data scrubbinh / validation


3. Commodity Hardware

For these systems to be affordable they must rely on commodity hardware that is inexpensive and easily accessible instead of purpose built systems.

Benefits of Scale Out

There are a number of significant benefits to these new scale out systems that meet the needs of big data challenges.


When data can grow in a single file system namespace the manageability of the system increases significantly and a single data administrator can now mange a  petabyte or more of storage versus 50 or 100 terabytes on a scale up system.

2. Elimination of stovepipes

Since these systems scale linearly and do not have the bottlenecks that scale up

systems create, all data is kept in a single file system in a single grid eliminationg the stovepipes introduced by the multiple arrays and files systems required.

3. Just in time scalability

As my storage needs grow I can add an appropriate number of nodes to meet my needs at the time I need them. With scale up arrays I would have to guess at the final size my data may grow while using that array which often led to the purchase of large data servers with only a few disks behind them initially so I would not hit bottleneck in the data server as I added disk.

4. Increased utilization rates

Since the data servers in these scale out systems can address the entire pool of storage there is no stranded capacity. There are five core tenets of scale out NAS should be simple to scale offer predictable performance , be efficient to operate always available and be proven to work in a large enterprises


EMC Isilon is the scale  –   out platform that delivers ideal storage for big data. Powered by the oneFS operating system, Isilon nodes are clustered to created a high –   performing single pool of storage.EMC Corporation announced in May 2011, the

world largest single file system with the introduction of emcisilon‟s new iq 108NL scale –  out NAS hardware product . Leveraging three terabyte (TB) enterprise –  class


hitachiultrastar drives in a 4u node, the 108NL scales to more than 15 petabytes (PB) in a single file system and single volume, providing the storage foundation for maximizing the big data opportunity.

EMC also announced isilon‟s new smartlock data retention software application ,delivering immutable protection for big data to ensure the integrity and continuity of  big data assets from initial creation to archival.

Object Based Storage

Object storage is based on a single . Flat addresss space that enables the automatic routing of data to the right storage systems and the right and protections levels within those systems according to it value and stage in the data life cycle.

Better Data Availability than RAID

In a properly configured object storage system content it replicated so that a minimum of to replicas assure continuous data availability. If a disk dies all the other disk in the cluster join in to replace the lost replicas while the system still runs at nearly full speed . Recovery takes only minutes with no interruption of data availability and no noticeable performancedegradation.

Provides unlimited capacity and scalability

In object storage systems there is no directory hierarchy and the object location does not have to be specified in the same way a directory path has to be known in order to retrieve it. This Nables object storage system to scaleout limits on the number of files (objects ), to petabytes and beyond without limits on the number of files ,file size or


file system capacity, such as the 2-terabyte restriction that is common for window and linux file systems.

Backups are Eliminated

With a well designed object storage system ,backups are not required . ultiples

replicas ensure that content is always available and an offsite disaster recovery replica can be automatically created if desired.

Automatic Load Balancing

A well designed object storage cluster is totally symmetrical which means that each node is independent provides an entry point into the cluster and runs the same code.

Companies that provide this are cleversafe,compiverde,amplidata ,caring,emc ,hitachi data systems (hitachi content platform),netapp (storage grid ) and scality.

2.2 Apache Hadoop has been the drivig force behind the growth of the big data industry . it is a frame work for running applications on large cluster buiyt of

commodity hardware. The hadoop framework transparaently provides applications  both reliability and data motion.

MapReduce  is the core of hadoop created at google in response to the problem of creating web search indexes , the map reduces frame work is the power house behind most of today big data processing . In addition to hadoop you will find map reduce inside MPP and no SQL databases such as vertica or mongoDB .The important


innovation of map reduce is the ability to take a query over a dataset, divide it and run it in parallel over multiple nodes. Distributing the computation solves the issures of data too large to fit into a single machine.

Combine this technique with commodity linux servers and you have a cost effective alternative to massive computing arrays.

HDFS - we discussed the ability of map reduce to distribute computation over multiple servers. For that computation to take palce, each server must have acess to the data. This is the role of HDFS , the hadoop distributed file system.

HDFS and mapreduce are robust .severs in a hadoop cluster can fail and not abort the computation process. HDFS ensures data is replicated with redundancy across the cluster. On completion of a calculation a node will write its results back intoHDFS . There are also restrictions on the data thatHDFS stores . Data may be structured and schemes be defined before storing the data .with HDFS making sense of the data is the responsibility of the developers code.

Why a company will be interested in hadoop?

The number one reason is that the company is interested in taking advantage of unstructured or semi structured data. This data will not fit well into a relational databases, but hadoop offers a scalable and relatively easy to program way to work with it. This category includes emails web serve logs instrumentation of online stores , images video and external data sets. All this data can contain information that is critical to this businesses orgranized by geographical area. All this data can contain information that is critical to this business and should reside in your data


warehouse,but it needs a lot of pre-processing and this pre-processing will not happen in oracle RDBMS .

For Example

The other reason to look into hadoop is for information that exists in the databse, but can‟t be efficiently processed within the database.this is a wide usecase and it is usually labeled ETL because the data is going out of an OLTP system and inot a data warehouse. You use hadoop when 99% of the work is in the t of etl processing the data into useful information.


Purpose built solutions like teredata, IBM/NETEZZA, EMC/Greenplum, SAP HANA( High-Performance Analytic appliance), HP Vertica and oracle exadata are forming a new category . Data appliances are one of the fastest growing categories in  bid data. Data appliances integrate databases, processing and storage in a integrated

3.0 Domain Wise Challenges in Big Data Era 3.1 Log Management


Log data does not fall into the convenient schemas required by relational databases. Log data is at its core, unstructured or in fact semi-structured which leads to a deafening cacophony of formats, the sheer variety in which logs are being generated is presenting a major problem in how they are analyzed . The emergence of big data has not only been driven by the increasing amount of unstructured data to be  processed in near real –  time , but also by the availability of new toolst to deal with these challenges. There are 2 things that don,t receive enough attention in the log management space. The 1st is real scalability which means thinking beyond what data centers can do. That inevitably leads to ambient cloud models for log management .Splunk has doe an amaing job of pioneering an ambient cloud mdel with th way they created and eventual consistency model which allow you to make a query to get a good enough answer quickly or a perfect answer in more time.

The 2nd  thing is security. Log data is next to useless if it is not nonrepudiatable . Basically all the log data in the world is not useful as evidence unless you can prove that nobody changed it.Sumo DataLogglySpluunkare the primary companies that currently have products around log management.

3.2 Data Integrity and reliability in the big data era

Consider standard business practices and how nearly all physical forms of documentation and transactions have evolved to become digitized versions and with them come the inherenllenges of validating not just the authenticity of their contents  but also the impact of acting upon an inavalid data set something which is highly  possible in today high velocity big data business environment . with view we can then  begin to identify the scale of the challenge. With cybercrime and insider threats


clearly emerging as a much mre profitable business the the criminal element , the need to validate and verify is going to become critical to all business documentation and related transactions even within the existing supply chains.

Keyless signature technology is a relatively new concept in the marke and will require a different set of perspectives when put under consideration . A keyless signature  provides an alternative method to key based technologies by providing proof and non

repudiation of electronic data using only hash functions for verification. The implementation of keyless signature is done via a globally distributed machine, taking hash values of data as inputs and returning keyless signatures that prove the time , integrity and origin of the input data.

A primary goal of the keyless signature technology is to provide mass-scale ,non-expiring data validation while elimanting the need for secrets or other forms of trust thereby reducing or even eliminating the need for more complex certificate based solutions as these are ripe with certificate management issues , including expiration and revocation.

As more orgainisations become affected by big data phenomenon , the clear implication is that many business will potentially be making business based on massice amounts of internal a third party data .

Consequently the demand for novel and trusted approaches to validating data will grow. Extend this concept to the ability to validate a virtual machine, switch logs or indeed the security logs and then multiply by the clear advantages that cloud


computing (public or private) has over the traditional datacenter design –   we will  begin to understand why keyless data integrity technology that can ensure self – 

validating data is a technology that is likely to experience adoption.

The ability to move away from reliance on a third party certification authority will be welcomed by many although this move from the traditionally accepted approach to verify data integrity needs to be more fully broadcasted and understood for more mass market adoption and acceptance.

Another solution for monitoring the stability , performance and security of your big data environment is from a company called Gazzang. Enterprises and SaaS solution  providers have new needs that re driven by the new infrastructures and opportunities

of cloud computing . For Example , business intelligence analysis use big data stores such as mongo db , hadoop and Cassandra . The data is spread across hundreds of server in order to optimize processing time and return business insight to the user. Leraging its extensive experience with cloud architectures and big data platform ,gazzang is delivering a Sass solution for the capture , management and analysis of massive volume of IT DATA. Gazzangzops is purpose built for monitoring big data  platforms and multiple cloud environments . The powerful engine collects and

correlates vast amounts of data from numerous sources in a variety of forms.

3.3 Backup Management in Big Data Era

For protection against user or application error ,asharbaig a senior analyst and consultant with the taneja group , said snapshots can help with big data backups. Big also recommends a local disk based system for quick and simple first –   level data


recovery problem. “ look for a solution that provide you an option for local copies of data so that you can do local restores which are much faster he said , having a local copy and having an image based technology to do fast image based snaps and replications does speed it up and takes care of the performance concern.

Faster Scanning Needed

One of the issures big data backup systems face is scanning each time the backup and archiving solutions start their jobs. Legacy data protection systems scan the file system each time a backup job is run and each time an archiving job is run. For file systems is big data Environment this can be time consuming. Commvault solution for the scanning issue in its impana data protection software is it one pass feature. According to commvault , one pass is an object level converged process for collecting  backup archiving and reporting data. The data is collected and moved off the primary system to a content store virtual repository for completing the data protection operations. Once a complete scan has been accomplished , the commvault software  places an agent on the file system to report on incremental backups making the  process even more efficient.

Casino doesn’t want to gamble on backups

Pechanga resort and casino in Temecula calif went live with a cluster of 50 EMC isilon X200 nodes in February to back up data from its surveillance cameras. The casino has 1.4 PB of usable isilon storage to keep the data, which is critical to operations because the casino must shutdown all gaming operations if its surveillance system is interrupted.


“In gaming we‟re mandated to have surveillance coverage ,” said Michael grimsley director of systems for Pechanga technology solutions group. If surveillance is down all gaming has to stop. If a security incident occurs their team pulls footage from the x200 nodes and moves it to worm compliant storage and back it up with networker software to emc data domain dd860 the duplication target appliances. The casino doesn‟t need tape for worm capability because worm is part of isilons smart lock software. Another possibility is adding replication to a DR site so the casino can recover quickly if the surveillance system goes down.

Scale out Systems

Another option to solving the performance and capacity issues is using a scale out  backup system one similar to scale out NAS,but built for data protection .you add nodes with additional performance and capacity resources as. the amount of protected data growschnogy. “Any backup architecture especially for the big data world has to officer balance the performance and the capacity properly said jefftofanosepatoninc chief technology officer .otherwise at the end of the day , it not a good solution for the customer and is a more expensive solution than it should be .

Sepaton s2100-es2 modular virtual tape library (VTL) was built for data intensive large enterprises. According to the company its is 64 bits processor nodes backup data at up to 43.2tb per hour , regardless of the data type and can store up to 1.6pb yoy can add up to eight performance nodes per cluster as your needs require and add disk shelves to add capacity.


There are currently three tree trends in the industry:

1. The NoSQL databases designed to meet the scalability requirements of distribution architectures and or schemaless data management requirements. 2. The NewSQL databases designed to meet the reqirements of distributed

architectures or to improves performance such that horizontal scalability is no longer needed.

3. The data grid /cache products designed to store data in memory to increase application and database performance .

Computer World Tam Harbert explored the skills and needs organizations are searching for in the quest to manage the big data challenge and also identified five  job titles emerging in the big data world .

Along with habert findings here are 7 new types job being created by big data : 1. Data Scientists : This emerging role is taking the lead in processing raw data and

determining what types of analysis would deliver the best results.

2. Data Architects : Organistaitons managing bid data need professional who will be able to build a data model and plan out roadmap of how and when various data sources and analytical will come online had how they will all fit together.

3. Data Visualizer : These days a lot of decision –  maker rely on information that is  presented to them in highly visual format –  either on dashboards with colorful

alerts and dials or in quick understand charts and graphs organizations need  professionals who can harness the data and put it in context , in layman language

exploring what the data means and how t will impact the company.

4. Data Change agents : - Every forward thinking organistation needs change agents usually an informal role who can evangelize and marshal the necessary resources


for new innovation and ways of doing business. Harbert predicts that data change in internal operations and processes based on data analytics. They need to be good communicators and six sigma background –  meaning they know how to apply statistics to improve quality on a continuous basis also help.

5. Data engineer/operators : these are the people that make the big data infrastructure hum on day to day basis. They develop the architecture that hels analyze and supply data in the way the business needs and make sure systems are performing smoothly says harbert.

6. Data stewards : not mentioned in harbert list but essential to any analytics-driven organization is the emerging the role of data steward.Every bit and byte of data across the enterprise should be owned by someone –  ideally a linne of business . Data Stewards ensure that data sourcesare properly accounted for and may also maintained a centralized repository as part of master data management approach in which there is one gold copy of enterprise data to be referenced .

7. Data Virtualization/cloud specialists :- Databases themselves are no longer as unique as they use to be . what matter now is the ability to build and maintain a virtualized data service layer in a consistent easy to access manner. Sometimes this is called databases a service . No matter what it called organization need  professional that can also build support these virtualized layer or clouds.

4.0 BigData use cases : 4.1 Potential use cases

The key to exploiting big data analytics is focusing on a compelling business opportunity as defined by use case what (what exactly are we trying to do ? ) what value is ther proving a hypothesis ?


Use cases are emerging in a variety of industries that illustrate different core competencies around analytics. Figure below illustrates some use cases along two dimensions data velocity and variety.



Insurance:-  -- Individualize auto –   insurance policies based on newly captured vehicle telemetry data . Insurer gains insight inot customer driving habits delivering 1) more accurate assessments of risk 2) individualized pricing based on actual individual customer driving habits 3) influence and motivate individual customer to improve their drivinghabits .

Travel :-- optimize buying experience through web log and social media data nalysis 1) travel site gain insight in not customer preferences and desires 2) up – selling  products by correlating current sales with subsequent browsing behavior increase  browse to buy conversions via customized offers and packages 3) deliver personalized

travel recommendations based on social media data .

Gaming –  Collect gaming data to optimize spend within and across games 1) games

company gains insight into likes , dislikes and relationships of it user 2)Enchance games to drive customer spend within games 3) recommend othecontenet based on


analysis of player connections and similar like . Create special offers or packages  based on browsing and buying behaiour.

4.2 Big data Actual Use Cases

Below graphic mentions the survey result undertaken by information week which indicated the % of respondents who would be opting for a open source solutions for Bd Data.

1. Use Case

Amazon will pay shoppers $5 to walk out of stores emptyhandedInteresting use of consumer data entry to power next generation retail price competition amazon is offering consumers up to $ 5 off on purchase if they compare prices using their mobile phone application in a store. The promotion will serve as a way for amazon to increase usage of it bar code scanning application while also collectiong intelligence on prices in the stores.

Amazon‟s price check app which is available for iphone and android allows shoppers to scan a bar code take a picture of an item or conduct a text search to find the lowest prices . Amazon is also asking consumer its still ofto submit the  prices of items with the app „ so amazon know offering the best prices . A great way to feed data inot it learningengine from brick and mortor retailers.This is an interesting trend that should terrify bricj and mortar retailer .while the

realtimeevery day low price information empower consumers it terrifies retailer who increasingly are feeling like showroom shoppers come to be check out the merchandise but uttimately decide to walk out and buy online instead.


2. Smart meters

1) Because of smart meters , electricity providers can read the meter once every 15 minutes reather than once a month . This not only eliminated the need to send some one for meter reading, but as the e is read once every fifteen minutes , electricity can be priced differently for peak and off peak hours .  pricing can be used to shape the demand curve during peak hours eliminationg the need for creating additional generating capacity just to meet peak demand , saving electicity providers millions of dollars worth of investment in generating capacity and plant maintenance costs.

2) Well there is a smart electric meter in a residence in texas and one of the electricity providers in the area is using the smart meter technology to shape the demand curve by offering free night time energy charges –  all night every night . All year long.

3) In Fact they promote their service as do your laundry or run the dishwasher at night and pay nothing for your energy charges. What txu energy is trying to do here is to reshape energy demand using pricing so as to manage peak time demand resulting in savings for both txu and customer . This wount have been  possible without smart electric meters.

4) T-mobile USA ---- has integrated big data across multiple it systems to combine customer transaction and interactions data in order to better predict customer defections. By leveraging social media data along with transactions data from CRM and billing systems , t mobile USA has been able to cut customer defections in half in a single quarter.


5) Us express provider of a wide r=variety of transportation solutions collects about a thousand data elements ranging from fuel usage to tire conditions to truck engine operations to gps information and uses this data for optimal fleet management and to drive productivity saving millions o dollars in operating costs.

6) Mclaren formula one racing team --- uses real –  time car sensor data during car races, identifies issues with its racing cars using predicatives analytics and take corrective actions proactively before it too late |

7) How morgan Stanley uses hadoop ---- Gary bhattarcharjee executive director of enterprises information management at the firm has worked with hadoop as early as 2008 and thought that it might provide a solutions .so the it department hooked up some old servers.

At the fountained head conference on hadoop In finance in new York  bhattacharjee said the investment bank has started by stringether 15 end of life  boxes . it allowed us to bring really cheap infrastructure into a framework and install hadoop and let it run.One area that bhattacharjee would talk about was in it and log analyisis.A typical approach would be a look at web logs and database logs to see problems but one log wouldn‟t shpow if a web delay was caused by a databse logs pu them inot hadoop and ran tim based correlations .now they can see market events and how they correlate with web issues and databases read write problems.


With analytics now embedded ito the culture of ford , the rise of big data analytics has created a whole host of new possibilities for the automaker generate internally from our business operations and also from our vehicle. We recognize that the volumes of data we generate internally –  from our business operations and also from our vehicle research activities as well as the universeof data that our customers live inn and our vehicle research activities as well as the universe of daa that our customers live in and that exists on the internet –  all of those things are hug opportunities for us that will likely require some new specialized techniques or platforms to manage, said ginder . our research organization is experimenting with haddo and we are trying to combine all of these various data sorce that we have accesto . we thing to sky is the limit . we recognize that we are  just kind of scraping the tip of the iceberg here.The other major asset that fordhs

going for it when it comes to bigdata is that hthe company is tracking enormpus amounts of useful data in both the product development process and the products themselves.

Ginder noted our manufacturing sites are all very well instrumental. Our vehicles are very well instrtmental. They closed loop control systems . There are many many sensors in each vehivle until now most of that information was in the vehicle , but we think ththat data andere opportunity to grab that data and

understand better how the car operated and how consumers use the vehicles and feed that informations back inot our design process and help optimize the user experience in the future as well.


Of course big data is about a lot more than just hearnessing all of the runaway data sources that mos companies are trying to grapple with it about structured data plus unstructured data . structure data is all the traditional stuff most companies have in their databases as the stuf like ford is talking about with sensors in its vehicles and assembly ) unstructured data is the stuff that now freely available across he internet , from public data now being exposed by government on sites such as in the us to treasure troves of consumer intelligence such as twiteer .mxing the two and coming up with new analysis is that big data is all about.

The amount of that data is only goingtassumption of big data is only own goin grow and there aopportunity for us to combine that external data with our internal data in new ways said ginder . for better forecasting or for better insight into  product design there are many many opportunities.

Ford is alos digging into the consumer intelligence aspect of unstructured data .Ginder said we recognize that the data on the internet is potentially insightful for understaning what our customer or our potential customer are looking for what their attitudes are so we do some sentiment analysis around blog post, comments and other types of content on the internet.

That kind of thing is pretty common and a lot of fortune 500 companies are doing similar kinds of things .however there another way that ford is uusing unstructured data from the web that is a little more unique and it tohas impacted the way the company predicits future sales of tit vehicles.


We use google trends which measures the popularity of search terms to help form ourwon internal sales forecasts ,ginder explained . Along with other internal data we have , we use that to build a better forecast , ginder explained . Along with other internal data we have we use that to buid a better forecast .it one of the inputs for oursals forecast . In the past it would justbe what we sold last week . ow it what we sold last weel plus the popularity of the search terms again, I think we are just scratching the surface . There a lot more I think we will be doing in the future.

Computer and electronics products and information sectors traded globally stand out as sctors that have already been experiencing very strong productively growth and that are poised to gain substaintially from the use of big data.

Two services sectors and insurance and government are positioned to benefit very strongly from big data as long as barriers ot it use can overcome.

Several sectos have experienced negative productivity growth probably indicationg that these sectos face strong systematic barriers to increasing  productivity. Among the remaing sectors we see that globally traded sectos ten to have experienced higher productivity growth while local services (mainly cluster E) have experienced lower growth.

While all sectors will have to overcome barriers to capture value from the use of  big data,barriers are structureally higher for some than for others . For Example ,


datadriven mindset and available data .capturing value in health care face challenges given the relatively low IT investment performed so far. Sectors such as retail , manufacturing and professiona services may have relatively lowe degrees of barriers to overcome for precisely the opposite reasons.

4.3 In IBM Big Data used for


speech recognition (SR) is the translation of spoken words into text. It is also known as "automatic speech recognition", "ASR. Some SR systems use "speaker independent speech recognition" while others use "training" where an individual speaker reads sections of text into the SR system. These systems analyze the person's specific voice and use it to fine tune the recognition of that person's speech, resulting in more

accurate transcription. Systems that do not use training are called "speaker independent" systems. Systems that use training are called "speaker dependent" systems.

Speech recognition applications include voice user interfaces such as voice dialling (e.g. "Call home"), call routing (e.g. "I would like to make a collect call"), domotic appliance control, search (e.g. find a podcast where particular words were spoken), simple data entry (e.g., entering a credit card number), preparation of structured documents (e.g. a radiology report), speech-to-text processing (e.g., word  processors or emails), and aircraft (usually termed Direct Voice Input).

2009 :- CLOUDThe future of the cloud is going to be a hybrid combination of public and private cloud, not one or the other. There will be times when you want to run a workload in a private cloud, then move it up to a public cloud, and later move it back again to your private cloud. We see a Microsoft private cloud as the first step towards  building a cloud that allows you to go into the public cloud, which is what we call


Windows Azure. With Microsoft, our cloud offerings are designed so that your  private cloud and public cloud work together.

The internet has made new sources of vast amount of data to business executives . Big data is comprised of data sets too large be handled by traditional systems. To remain competitive, business executives need to adopt new technologies and techniques emerging e to big data. Big data includes structured data , semi structured and unstructured data. structured data are those data formatted for use in a database management system. Semi structured and unstructured data include all type of unformatted data including multimedia and social media content. Big data are also  provided by myriad hardware objects, including sensors and actuators embedded in  physical objects,

Web Based Questionnaires : A new and inevitably growing methodology is the use of Internet based research. This would mean receiving an e-mail on which you would be click of an address that would take you to secure web-site to fill in a questionnaire. This type of research is often quicker and less detailed. Some disadvantages of this method include the exclusion of people who do have a computer or are unable to access a computer. Also the validity of such surveys are in question as people might  be in a hurry to complete it and so might not give accurate responses. (https:// h_LX7NksW5GR_frU5wnhA_OPVAY/viewform)

Questionnaires often make use of checklist , checkbox and rating scale. These devices DATA COLLECTION SUMMARY


 behaviors , characteristics , or other entities that the researcher is looking for Either the researcher or survey participant simply checks whether each item on the list is observed, present or true or vice versa. A Rating Scale is more useful when behavior needs to be evaluated on a continuum. They are also known as LikertScaels.

The biggest challenge for any huge organisation is to figure out who should own the  big data initiatives that straddle the entire organisation. Big Data is a must in every organisation as there is always a chance of losing a big chunk of the important data. no idea abt big data Great cloud backup Big data is collocation of all the relevant data. big data should be have backup Student DATA Big data is useful for viewing structured data. I don't deal with big data on day to day basis. Hence not able to  justify. other no idea about Big data Harddisk Most of the organizations maintain a mix of data sets in various forms. Irrespective of your profession apps are require to make your data more accessible, usable and valuable. More reliable Should have more capacity for Data use . Big data refers to groups of data that are so large and unwieldy that regular database management tools have difficulty capturing, storing, sharing and


managing the information. I don't know any thing about Big data big data Big Data Required More Efficient Big data Should be stored in centralised format The file which is more than 10 MB. Big Data is not limited to just email but its more about the  business data running on servers (Oracle database, data backup of servers,

etc) none no idea we are use many types of data formats,for security reason we take daily backup. Use cloud Service for video and jpeg format require advance technology cloud computing not yet used, but aware of what big data is. Big data is future. no idea abt big data It's a huge hype with only top guns moving into the technology. The investment is high and seems risk prone. all the database should be stored in centralised data should be in cloud Big data require more security Provide custopmization in big dataBig data should be disaster reovery Accounts Statement data should be in Icloud. It should be easily accessable for the person who is storing it .. should provide in cloud

Do you have any Suggestions on the concept of Big Data?

no big data cloud backup NA big data should be have backup Information management is the most crucial in the organizations, hence more research on data management and analytics is required. other i suggestion data should be in cloud  backup,it is very much secure & better, Thanks Purchase New USB Hard disk Drive

And Copy All Data For economic feasibility in any successful organisation ,it is essential to device ways and means to handle "big data" without driving up the hardware costs. More reliable No 1) Backup concept needs to be highlighted in this survey. 2) Software used should be asked 3) Kind of data to be backed up should be asked 4) Retrieval procedure should be asked 5) Incase of backup is corrupted there should be a concept of fail safe module which should be discussed Store more Hard disk Big data Should be stored in centralised format The file which is more than 10


MB. none Same as above no idea If daily back up is taken then it would be of great help and if possible back up is taken dept. wise then the time consumed for retriving the data would be reduced. require advance technology no idea abt big data data should be in cloud cloud computing Use cloud Serice for video and jpeg format Big data require more security Provide custopmization in big data Big data should be disaster reovery nope, not yet data should be in Icloud. It should be easily accessable for the person who is storing it .. should provide in cloud

Number of daily responses

1.  Nearly half the data (49%) is unstructured (text), while 51% is structured. Also, about 70% of the data is from internal sources.

2. Logistics and finance expect the greatest ROI, although sales and marketing have a bigger share (30%) of the Big Data budget

3. Monitoring how customers use their products to detect product and design flaws is seen as a critical application for Big Data

4. About half of the firms surveyed are using Big Data, and many of them projected  big returns for 2014

5. Big split in spending on Big Data, with a minority of companies spending massive amounts and a larger number spending very little
