What information is provided by the descriptive analytics employed at Magpie Sensing? • 2. What type of support is provided by the predictive analytics employed at Magpie Sensing? • The predictive analytics use the descriptive data to alert users when a unit is not configured properly for storing the products. It also sends an alert when average temperature and compressor cycle runs signal that a temperature may go out of range (for example, after a power failure) or that there may have been a human error, such as failure to shut a door. • These analytics tell users about a problem that may occur, giving them time to prevent the problem. • The descriptive analytics monitor and report the properties of the cold storage system, including the set point of each thermostat, the typical range of temperatures in the system, and the duty cycle of each compressor. These values tell trained personnel whether each storage unit is properly configured for storing particular products. Dr. Chen, Business Intelligence 19 • 3. How does prescriptive analytics help in business decision making? • Prescriptive analytics guides decision makers to the alternative with the greatest benefits. In Magpie’s cold chain system, prescriptive analytics uses data about storage unit performance to help buyers select the best storage units. And based on data about storage system efficiency and product sensitivity, prescriptive analytics guides decisions about where to distribute particular products in the supply chain. • 4. What are possible ways to report actionable information in real time to the concerned users of the system? • The system uses shippable wireless monitors. These continuously measure temperature, humidity, and location and transmit the data to the computer that analyzes the data. Dr. Chen, Business Intelligence 20 Dr. Chen, Business Intelligence • 5. What other situations might need real-time monitoring applications? • Answers will vary, but students should consider other systems where current performance provides information about changes or decisions that would improve future performance. • Examples include monitoring inventory levels at a manufacturing company to determine when to replenish stocks, monitoring sales in a store to identify when and how to adjust the mix of products, and monitoring patient status in a hospital to identify situations where different treatment is required or devices are malfunctioning. 21 22 Dr. Chen, Business Intelligence Fig. 1.1: Business Pressures – Responses – Support Model 1.2 Changing Business Environment & Computerized Decision Support Model [Business Pressure] • Companies are moving aggressively to computerized support of their operations => Business Intelligence • Business Pressures–Responses–Support Model Business pressures result of today's competitive business climate Responses to counter the pressures Support to better facilitate the process for making (or improving) better decision [Response/Action] [IT/Computerized Support] Dr. Chen, Business Intelligence Be Reactive, Anticipative, Adaptive, and Proactive Managers must respond quickly, innovatively, agile. _________ and be ______ 23 Dr. Chen, Business Intelligence AHP and Data mining tool (Rapid-Miner) 24 4 Table 1.1 Business Environment Factors that Create Pressures on Organizations The Business Environment • The environment in which organizations operate today is becoming more and more complex, creating: FACTOR DESCRIPTION Markets Strong competition Expanding global markets Blooming electronic markets on the Internet Innovative marketing methods Opportunities for outsourcing with IT support Need for real-time, on-demand transactions Desire for customization Desire for quality, diversity of products, and speed of delivery Customers getting powerful and less loyal More innovations, new products, and new services Increasing obsolescence rate Increasing information overload Social networking, Web 2.0 and beyond Growing government regulations and deregulation Workforce more diversified, older, and composed of more women Prime concerns of homeland security and terrorist attacks Necessity of Sarbanes-Oxley Act and other reporting-related legislation Increasing social responsibility of companies Greater emphasis on sustainability Consumer demand opportunities, and problems.

Dr. Chen, Business Intelligence 30 5 Business Intelligence (BI) – cont. The Process of BI • BI is an umbrella term that combines architectures, tools, databases, analytical tools, applications, and methodologies • The first is the business aspect of BI the need to get the most value out of information. this need hasn’t really changed in over fifty years (although the increasing complexity of the world economy means it’s ever harder to deliver). • The second is the IT aspect of BI what technology is used to help provide the business need. This obviously does change over time — sometimes radically. • In summary, BI helps transform data, to information (and knowledge), to decisions and finally to action. 31 Dr. Chen, Business Intelligence Data Warehouse + •Situations •Performance Informed and better Decisions ACTIONS (DW vs. DB) Definition of BI: •BI can be considered as an integrated solution suite, where its power and functionality may be utilized by anyone who touches data within a particular context. •In general, BI is the application of end-user query, reporting, dashboards, and other non-programming technologies to provide information that is not available to the business using traditional programming methods and services. (The New Era of Enterprise BI, Mike Biere, 2001) 32 Dr. Chen, Business Intelligence Fig. 1.2: The Evolution of BI Capabilities A Brief History of BI • The term BI was coined by the Gartner Group in the mid-1990s • However, the concept is much older 1970s — MIS reporting — static/periodic reports 1980s — Executive Information Systems (EIS) 1990s — OLAP, dynamic, multidimensional, ad-hoc reporting -> coining of the term “BI” 2010s - Data/Text/Web Mining; Web-based Portals, Dashboards, Big Data, Social Media, and Visual Analytics 2020s - yet to be seen Video: History of Business Intelligence (10m 36s) Dr. Chen, Business Intelligence 33 34 Dr. Chen, Business Intelligence • Metadata: The Architecture of BI data about data – data dictionary of a database • ETL: Extraction, transformation and load (raw data) – taking data from a transactions processing system, cleaning it up, and moving to a data warehouse. • A BI system has four major components: warehouse with its source data 1. a data _________, analytics (or analytical environment) 2. business ________, a collection of tools for manipulating, mining, and analyzing the data in the data warehouse; 3. business performance _________ management _________ (BPM) for monitoring and analyzing performance interface (e.g., dashboard) 4. a user _______ • Data Warehouse: Mostly historical data for analysis of corporate performance, can contain current data for online transaction processing – e.g. Teradata warehouse system • Data Marts: Smaller (particular subject or department) and more focused than a data warehouse - marketing data mart as a subset of a corporate data warehouse • DSS: Decision Support System - System to help managers in decision making, e.g., for mortgage loan decisions, project selections, etc. Dr. Chen, Business Intelligence 35 Dr. Chen, Business Intelligence 36 6 Fig. 1.3: A High-level Architecture of BI 1. 2.

The tables are related by the single column they have in common: Owner_ID. • By relating tables to one another, redundancy of we can reduce ____________ data and improve database performance. • The process of breaking tables apart and thereby reducing data redundancy is called normalization 60 _______________. 10 OLTP vs. OLAP (cont.) OLTP vs. OLAP (cont.) • In order to keep our transactional databases running quickly and smoothly, we may wish to create a data warehouse. A data warehouse is a type of large database (including both current and historical data) that has been denormalized _____________ and archived. • Denormalization is the process of intentionally combining some tables into a single table in spite of the fact that this may introduce duplicate data in some columns. • Most relational databases which are designed to handle a high number of reads OLTP and writes (updates and retrievals of information) are referred to as ________ (OnLine Transaction Processing) systems. • OLTP systems are very efficient for high volume activities such as cashiering, where many items are being recorded via bar code scanners in a very short period of time. • However, using OLTP databases for analysis is generally not very efficient, because in order to retrieve data from multiple tables at the same time, a query joins must be used. containing ________ Fig. Extra-b: A combination of the tables into a single dataset. 61 Dr. Chen, Business Intelligence • The figure depicts what our simple example data might look like if it were in a data warehouse. When we design databases in this way, we reduce the number of joins necessary to query related data, thereby speeding up the process of analyzing our data. OLAP (OnLine Analytical • Databases designed in this manner are called __________ Processing) systems. Dr. Chen, Business Intelligence 62 OLTP vs. OLAP (cont.) 1.6 Successful BI Implementation • Transactional systems and analytical systems have conflicting purposes when it comes to database speed and performance. For this reason, it is difficult to design a single system which will serve both purposes. This is why data warehouses generally contain archived data. Archived data are data that have been copied out of a transactional database. • Denormalization typically takes place at the time data are copied out of the transactional system. It is important to keep in mind that if a copy of the data is made in the data warehouse, the data may become out-ofsynch . This happens when a copy is made in the data warehouse and ______ then later, a change to the original record is made in the source database. • Data mining activities performed on out-of-synch records may be useless, or worse, misleading. • An alternative archiving method would be to move the data out of the transactional system. This ensures that data won’t get out-of-synch, however, it also makes the data unavailable should a user of the transactional system need to view or update it. Dr. Chen, Business Intelligence • Implementing and deploying a BI initiative is a lengthy, expensive, and risky endeavor! • Success of a BI system is measured by its widespread usage for better decision making • The typical BI user community includes Not just the top executives (as was for EIS) All levels of the management hierarchy Provide what is needed to whom he/she needs it • A successful BI system must be of benefit to the enterprise as a whole… 63 BI for Business Strategy BI - Alignment with Business Strategy • Strategy should be aligned with BI/DW – has the capability to execute the initiative by establishing a BI Competency Center (BICC) which can: • To be successful, BI must be aligned with the company’s business strategy (think about IS/IT Triangle Strategy Model). BI cannot/should not be a technical exercise for the information systems department • BI changes the way a company conducts business by improving business processes, and transforming decision making to a more data/fact/information driven activity • BI should help execute the business strategy and not be an impediment for it!

Why did Nationwide need an enterprise-wide data warehouse? 2. How did integrated data drive the business value? 3. What forms of analytics are employed at Nationwide? 4. With integrated data available in an enterprise data warehouse, what other applications could Nationwide potentially develop? • Two aspects for studying “Big Data” storing and __________ processing /analyzing “Big Data” _______ computation to the data instead of pushing • Push ___________ data to a computing mode. • More on big data and related analytics tools and techniques are covered in Chapter 6. Dr. Chen, Business Intelligence 73 • 1. Why did Nationwide need an enterprise-wide data warehouse? • With more than 100 business units offering a variety of products, Nationwide experienced duplication of effort in gathering data, analyzing it, and generating reports. Data-processing environments were widely dissimilar, and there was extreme data redundancy, resulting in higher expenses. • Mergers and acquisitions only added to the difficulty and cost. A single, authoritative data warehouse would apply best practices and provide clean, consistent, and complete data. Dr. Chen, Business Intelligence 74 • 2. How did integrated data drive the business value? • Integrated data about customers improved marketing campaigns and better targeted communications, which improved customer satisfaction and retention, as well as contributing to a gain in sales. • Integrated financial data made financial reporting faster and more efficient and added tools for better risk assessment and decision support. • Integrated data following mergers fostered smoother integration of businesses. Integrated data for reporting gave agents easy access to reports within seconds rather than days, significantly improving productivity. 75 • 3. What forms of analytics are employed at Nationwide? • It uses the three basic types of business analytics. • The company’s data warehouse supports descriptive analytics for all functions. For example, the data describes customer behavior, financial performance, and policy information. • It uses predictive analytics in the Customer Knowledge Store to identify the kinds of customer interaction that are important for customers at different points in their lives. Dr. Chen, Business Intelligence Dr. Chen, Business Intelligence Dr. Chen, Business Intelligence 76 • 3. (cont.) • At the level of prescriptive analytics, the Financial Performance Management system applies financial data to a decision support system. • You may identify additional examples of these three categories. Optionally, you may also refer to analytics applied to different domains, such as marketing analytics, financial analytics, and even insurance analytics. 77 Dr. Chen, Business Intelligence 78 13 From Data to Knowledge: How Can Organization Gain Competitive Advantage?
