1 Intro to Big Data and Business Intelligence Anjana Susarla Eli Broad College of Business What is Business Intelligence A Simple Definition: The applications and technologies transforming Business Data into Action Business intelligence (BI) is a business management term refers to applications and technologies which are used to gather, provide access to, and analyze data and information about their company operations. Business intelligence systems can help companies gain more comprehensive knowledge of the factors affecting their business, and help companies to make better business decisions. YouTube: What is BI?

2 Data, information, and knowledge Data a collection of raw value elements or facts used for calculating, reasoning, or measuring. Information the result of collecting and organizing data in a way that establishes relationship between data items, which thereby provides context and meaning Knowledge the concept of understanding information based on recognized patterns in a way that provides insight to information. 3 Driving force - Big Data A collection of data sets so large and complex that it becomes awkward to work with using on-hand database management tools. Difficulties include capture, storage, search, sharing, analysis, and visualization. The trend to larger data sets is due to the additional information derivable from analysis of a single large set of related data, as compared to separate smaller sets with the same total amount of data. 4 Guest lecture AESC310

3 5 ISQS7339, Fall 01 Zettabyte (ZB) A quantity of information or information storage capacity equal to 10 1 bytes or 1,000 exabytes. As of April 01, no storage system has achieved one zettabyte of information. The combined space of all computer hard drives in the world was estimated at approximately 160 exabytes in 006. Seagate reported selling 330 exabytes worth of hard drives during the 011 Fiscal Year. As of 009, the entireworld Wide Web was estimated to contain close to 500 exabytes.this is a half zettabyte. 1,000,000,000,000,000,000,000 bytes = bytes = 10 1 bytes 6 Guest lecture AESC310 3

4 Data Scale 7 Market "Big data" has increased the demand of information management specialists - major companies have spent more than $15 billion for this. This industry is worth more than $100 billion and growing at almost 10% a year. 4.6 billion mobile-phone subscriptions worldwide and between 1 billion and billion people accessing the internet. The world's effective capacity to exchange information through telecommunication networks was 81 petabytes in 1986, 471 petabytes in 1993,. exabytes in 000, 65 exabytes in 007 It is predicted that the amount of traffic flowing over the internet will reach 667 exabytes annually by Guest lecture AESC310 4

5 Approach - Cloud Computing Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts remote services with a user's data, software and computation. Buzzword: SaaS/IaaS/PaaS 9 Distributed business intelligence Deal with big data the open & distributed approach LAMP Hadoop MapReduce HDFS NOSQL Zookeeper Storm Guest lecture AESC310 5

6 Apache Hadoop An open-source software framework for storage and large scale processing of data-sets on clusters of commodity hardware. The Apache Hadoop framework is composed of the following modules : Hadoop Common - contains libraries and utilities needed by other Hadoop modules Hadoop Distributed File System (HDFS). HadoopYARN - a resource-management platform responsible for managing compute resources in clusters and using them for scheduling of users' applications. Hadoop MapReduce - a programming model for large scale data processing. Apache Hadoop's MapReduce and HDFS components originally derived respectively from Google's MapReduce and Google File System (GFS) papers. 1 1 A Multi-node Hadoop Cluster 1 Guest lecture AESC310 6

10 1 9 ISQS 6339, Data Mgmt & BI Hadoop : Big data's big leap forward The new Hadoop is the Apache Foundation's attempt to create a whole new general framework for the way big data can be stored, mined, and processed. The biggest constraint on scale has been Hadoop s job handling. All jobs in Hadoop are run as batch processes through a single daemon called JobTracker, which creates a scalability and processing-speed bottleneck. Hadoop uses an entirely new job-processing framework built using two daemons: ResourceManager, which governs all jobs in the system, and NodeManager, which runs on each Hadoop node and keeps the ResourceManager informed about what's happening on that node. 0 Guest lecture AESC310 10

11 MapReduce.0 YARN (Yet Another Resource Negotiator) 1 The process of BI Data -> information -> knowledge -> actionable plans Data -> information: the process of determining what data is to be collected and managed and in what context Information -> knowledge: The process involving the analytical components, such as data warehousing, online analytical processing, data quality, data profiling, business rule analysis, and data mining Knowledge -> actionable plans: The most important aspect in a BI process Guest lecture AESC310 11

12 Actionable Knowledge An information asset retains its value on if the converted knowledge is actionable. Need some methods for extracting value from knowledge This is not a technical issue but an organizational one need empowered individuals in the organization to take the action There is an issue of Return on Investment (ROI) 3 BI Problems Structured Detecting Credit card fraud Setting Loan parameters Market segmentation/mass customization Deciding Marketing mix Customer Churn Reducing employee turnover Improving Quality/Efficiency Unstructured Data exploration Utilization of resources (stored knowledge) to maximum effectiveness 4 Guest lecture AESC310 1

15 Big data is at the foundation of all the megatrends that are happening today, from social to mobile to cloud to gaming. Chris Lynch, Vertica Systems Big data is not about the data Gary King, Harvard University, making the point that while data is plentiful and easy to collect, the real value is in the analytics Guest lecture AESC310 15

16 There were 5 exabytes of information created between the dawn of civilization through 003, but that much information is now created every days. Eric Schmidt, of Google, said in 010 Information is the oil of the 1st century, and analytics is the combustion engine. Peter Sondergaard, Gartner Research Guest lecture AESC310 16

17 I keep saying that the sexy job in the next 10 years will be statisticians, and I m not kidding Hal Varian, Google You can have data without information, but you cannot have information without data. Daniel Keys Moran, computer programmer and science fiction author Guest lecture AESC310 17

18 Hiding within those mounds of data is knowledge that could change the life of a patient, or change the world. Atul Butte, Stanford School of Medicine Errors using inadequate data are much less than those using no data at all. Charles Babbage, inventor and mathematician Guest lecture AESC310 18

19 To call in the statistician after the experiment is done may be no more than asking him to perform a post mortem he may be able to say what the experiment died of. Ronald Fisher, biologist, geneticist and statistician Without big data, you are blind and deaf in the middle of a freeway Geoffrey Moore, management consultant and theorist Guest lecture AESC310 19
