- 3. INTRODUCTION • ‘Big Data’is similar to ‘small data’, but bigger in size • but having data bigger it requires different approaches: • Techniques, tools and architecture • an aim to solve new problems or old problems in a better way • Big Data generates value from the storage and processing of very large quantities of digital information that cannot be analyzed with traditional computing techniques. 10/1/2015 3
- 4. WHAT IS BIGDATA • Walmart handles more than 1 million customer transactions every hour. • Facebook handles 40 billion photos from its user base. • Decoding the human genome originally took 10years to process; now it can be achieved in one week. 10/1/2015 4
- 5. THREE CHARACTERISTICS OFBIG DATA V3S Volume •Data quantity Velocity •Data Speed Variety •Data Types 10/1/2015 5
- 6. 1ST CHARACTER OFBIG DATA VOLUME •A typical PC might have had 10 gigabytes of storage in 2000. •Today, Facebook ingests 500 terabytes of new data every day. •Boeing 737 will generate 240 terabytes of flight data during a single flight across the US. • The smart phones, the data they create and consume; sensors embedded into everyday objects will soon result in billions of new, constantly-updated data feeds containing environmental, location, and other information, including video. 10/1/2015 6
- 7. 2ND CHARACTER OFBIG DATA VELOCITY • Click streams and ad impressions capture user behavior at millions of events per second • high-frequency stock trading algorithms reflect market changes within microseconds • machine to machine processes exchange data between billions of devices • infrastructure and sensors generate massive log data in real-time • on-line gaming systems support millions of concurrent users, each producing multiple inputs per second. 10/1/2015 7
- 8. 3RD CHARACTER OFBIG DATA VARIETY • Big Data isn't just numbers, dates, and strings. Big Data is also geospatial data, 3D data, audio and video, and unstructured text, including log files and social media. • Traditional database systems were designed to address smaller volumes of structured data, fewer updates or a predictable, consistent data structure. • Big Data analysis includes different types of data 10/1/2015 8
- 9. STORING BIG DATA Analyzingyour data characteristics • Selecting data sources for analysis • Eliminating redundant data Overview of Big Data stores • Data models: key value, graph, document, column- family • Hadoop Distributed File System • HBase • Hive 10/1/2015 9
- 10. PROCESSING BIG DATA Integratingdisparate data stores • Mapping data to the programming framework • Connecting and extracting data from storage • Transforming data for processing • Subdividing data in preparation for Hadoop MapReduce Employing Hadoop MapReduce • Creating the components of Hadoop MapReduce jobs • Distributing data processing across server farms • Executing Hadoop MapReduce jobs • Monitoring the progress of job flows 10/1/2015 10
- 11. THE STRUCTURE OFBIG DATA Structured • Most traditional data sources Semi-structured • Many sources of big data Unstructured • Video data, audio data 11 10/1/2015
- 12. WHY BIG DATA •Growth of Big Data is needed – Increase of storage capacities – Increase of processing power – Availability of data(different data types) 10/1/2015 12
- 13. WHY BIG DATA •FBgenerates 10TB daily •Twitter generates 7TB of data Daily •IBM claims 90% of today’s stored data was generated in just the last two years. 10/1/2015 13
- 14. HOW IS BIGDATA DIFFERENT? 1) Automatically generated by a machine (e.g. Sensor embedded in an engine) 2) Typically an entirely new source of data (e.g. Use of the internet) 3) Not designed to be friendly (e.g. Text streams) 4) May not have much values • Need to focus on the important part 14 10/1/2015
- 15. BIG DATA SOURCES Users Application Systems Sensors Largeand growing files (Big data files) 10/1/2015 15
- 16. DATA GENERATION POINTS EXAMPLES MobileDevices Readers/Scanners Science facilities Microphones Cameras Social Media Programs/ Software 10/1/2015 16
- 17. BIG DATAANALYTICS • Examininglarge amount of data • Appropriate information • Identification of hidden patterns, unknown correlations • Better business decisions: strategic and operational • Effective marketing, customer satisfaction, increased revenue 10/1/2015 17
- 18. TYPES OF TOOLSUSED IN BIG-DATA • Where processing is hosted? • Distributed Servers / Cloud (e.g. Amazon EC2) • Where data is stored? • Distributed Storage (e.g. Amazon S3) • What is the programming model? • Distributed Processing (e.g. MapReduce) • How data is stored & indexed? • High-performance schema-free databases (e.g. MongoDB) • What operations are performed on data? • Analytic / Semantic Processing 10/1/2015 18

- 20. RISKS OF BIGDATA • Will be so overwhelmed • Need the right people and solve the right problems • Costs escalate too fast • Isn’t necessary to capture 100% • Many sources of big data is privacy • self-regulation • Legal regulation 20 10/1/2015
- 21. HOW BIG DATA IMPACTSON IT • Big data is a troublesome force presenting opportunities with challenges to IT organizations. • By 2015 4.4 million IT jobs in Big Data ; 1.9 million is in US itself • India will require a minimum of 1 lakh data scientists in the next couple of years in addition to data analysts and data managers to support the Big Data space. 10/1/2015 21
- 22. BENEFITS OF BIGDATA •Real-time big data isn’t just a process for storing petabytes or exabytes of data in a data warehouse, It’s about the ability to make better decisions and take meaningful actions at the right time. •Fast forward to the present and technologies like Hadoop give you the scale and flexibility to store data before you know how you are going to process it. •Technologies such as MapReduce and Hive enable you to run queries without changing the data structures underneath. 10/1/2015 22
- 23. BENEFITS OF BIGDATA • Our newest research finds that organizations are using big data to target customer-centric outcomes, tap into internal data and build a better information ecosystem. • Big Data is already an important part of the $64 billion database and data analytics market • It offers commercial opportunities of a comparable scale to enterprise software in the late 1980s • And the Internet boom of the 1990s, and the social media explosion of today. 10/1/2015 23
- 24. FUTURE OF BIGDATA • $15 billion on software firms only specializing in data management and analytics. • This industry on its own is worth more than $100 billion and growing at almost 10% a year which is roughly twice as fast as the software business as a whole. • The McKinsey Global Institute estimates that data volume is growing 40% per year, and will grow 44x between 2009 and 2020. 10/1/2015 24
