  2. “Data Analysis, Where You Don’t Know the Second Question to Ask Until You See the Answer to the First One.” • Tracking race competitors from each of event, and having unbelievable success selling products to them. • Want to match competitors to personal trainers in same locale. • Earn referral fee. • How to track them? Mailing address? IP address? • Got data and Excel to start. • Serious data mining needs a data mart.

  3. Event Driven Alert - A Scenario • Three transactions were posted in a credit account while the account holder was traveling in summer 2010: • Ranch 99 San Jose, California $102.33 Aug. 1, 2010 • Exxon Austin, Texas $99.12 August 3, 2010 • Exxon Houston, Texas $120.44 August 5, 2010 • What action will you (the credit company) take and why? • How the scenario can be detected?

  4. CRM and Data Mining (BI)Example • A Grocery store in U.K. with the following “patterns” found: • Every Thursday afternoon • Young Fathers (why?) shopping at store • Two of the followings are always included in their shopping list • Diapers and • Beers • What other decisions should be made as a store manager (in terms of store layout)? • Short term vs. Long term • This is an example of cross-selling • Other types of promotion: up-sell, bundled-sell • IT (e.g., BI) helps to find valuable information then decision makers make a timely/right decision for improving/creating competitive advantages.

  5. Q/A • Can the “patterns” in the grocery store example be produced from its Database? • Y/N • Why? • It only can be produced from its “Data Warehouse” using a kind of “data mining” software.

  6. Study Questions Q1: How do organizations use business intelligence (BI) systems? Q2: What are the three primary activities in the BI process? Q3: How do organizations use data warehouses and data marts to acquire data? Q4: How do organizations use reporting applications? Q5: How do organizations use data mining applications? Q6: How do organizations use BigData applications? Q7: What is the role of knowledge management systems? Q8: What are the alternatives for publishing BI? Q9: 2026?

  7. Q1: How Do Organizations Use Business Intelligence (BI) Systems? • Information systems generate enormous amounts of operational data that contain patterns, relationships, clusters, and trendsabout customers, suppliers, business partners, and employees that can facilitate management, especially planning and forecasting. • Business intelligence (BI) systems produce such information from operational data. • Data communications and data storage are essentially free, enormous amounts of data are created and stored every day. • 12,000 gigabytes per person of data, worldwide in 2009

  8. Why do organizations need business intelligence? • BI systems are computer programs provide valuable information for decision making. • Three primary BI systems: • __________ tools read data, process them, and format the data into structured reports (e.g., sorting, grouping, summing, and averaging) that are delivered to users. They are used primarily for assessment. RFM (Recency, Frequency, and Monetary Value) is one of the tool for reporting. • ____________ tools process data using statistical, regression, decision tree, and market basket techniques to discover hidden patternsand relationships, and make predictionsbased on the results • ___________ _________ tools store employee knowledge, make it available to whomever needs it. These tools are distinguished from the others because the source of the data is human knowledge. Reporting Data-mining Knowledge management

  9. Q1: How Do Organizations Use Business Intelligence (BI) Systems? Components of Business Intelligence System Fig 9-1: Components of a Business Intelligence System

  10. Tools vs. Applications vs. Systems • BI ____ (e.g., decision-tree analysis) is one or more computer programs. BI tools implement the logic of a particular procedure or process. • BI __________ is the use of a tool on a particular type of data for a particular purpose. • BI _______ is an information system having all five components (what are they?) that delivers results of a BI application to users who need those results. tool application system

  36. Possible Problems with Source Data Curse of dimensionality • Fig 9-14 Possible Problems with Source Data

  37. Q4: How Do Organizations Use Reporting Applications? • Create meaningful information from disparate data sources • Deliver information to user on time • Basic operations: • Sorting   • Filtering • Grouping   • Calculating • Formatting

  38. What are typical reporting applications? • RFM Analysis allows you to analyze and rank customers according to purchasing patterns as this figure shows. • __________:How recently a customer purchased items? => leads and opportunities • __________: How frequently a customer purchased items? => retention • __________ Value: How much a customer spends on each purchase? => profitability • RFM Analysis • Sort the data by date (for recency), times (for frequency), and purchase amount (for money), respectively • Divide the sorted data into five groups • Assign 1 to top 20%, 2 to next 20%, 3 to the third 20%, 4 to the fourth 20% and 5 to the bottom 20%. • The _______ the score, the better the customer. Recency Frequency Monetary lower

  39. RFM Analysis: Example RFM Scores R F M lower The ______ the score, the better the customer, and, consequently, the more profit the company will be. Fig 9-16 Example of RFM Scores Organizations can find their most valuable customers through “RFM”: • Recency: How recently a customer purchased items? => leads and opportunities • Frequency: How frequently a customer purchased items? => retention • MonetaryValue: How much a customer spends on each purchase? => profitability _ecently _requently _oney

  40. Interpreting RFM Score Results • Ajax has ordered recently and orders frequently. M score of 3 indicates it does not order most expensive goods. • A good and regular customer but need to attempt to up-sellmore expensive goods to Ajax • Bloominghams has not ordered in some time, but when it did, ordered frequently, and orders were of highest monetary value. • May have taken its business to another vendor. Sales team should contact this customer immediately. • Caruthers has not ordered for some time; did not order frequently; did not spend much. • Sales team should not waste any time on this customer. • Davidson in middle • Set up on automated contact system or use the Davidson account as a training exercise 80/20 Rule (Pareto Principle)

  41. RFM Analysis Classification Scheme

  42. A sales team should attempt to up-sell more expensive products to a customer who has an RFM score of ________. A) 311 B) 551 C) 113 D) 542 Answer: ______ C

  43. OLAP and its Applications • Online Analytical Processing (OLAP), a second type of reporting tool, is more generic than RFM. • OLAP provides you with the dynamic ability to sum, count, average, and perform other arithmetic operations on groups of data. Reports, also called OLAP cubes. • What software and function that enable you to create OLAP and its applications? • ANSWER • EXCEL with • Pivot table

  44. Example of Grocery Sales OLAP Reporthttp://dwreview.com/OLAP/ http://www.tableausoftware.com • Online Analytical Processing (OLAP) cubes, use • Measures which are data items of interest. In the figure below a measure is Store Sales Net . • Dimensions which are characteristics of a measure. In the figure below a dimension is Product Family. OLAP Product Family by Store Type • Fig 9-17 Example Grocery Sales OLAP Report

  45. Example of Expanded Grocery Sales OLAP Report Drill down • Fig 9-18 Example of Expanded Grocery Sales OLAP Report

  46. Example of Drilling Down into Expanded Grocery Sales OLAP Report • Fig 9-19 Example of Drilling Down into Expanded Grocery Sales OLAP Report

  47. OLAP servers are special products that 1) read data from an operational database, 2) perform some preliminary calculations, and then3) store the results in an OLAP database Role of OLAP Server & OLAP Database Third-party vendors provide software for more extensive graphical displays

  48. On-Line Analytic Processing (OLAP) • Enables mangers and analysts to interactively examine and manipulate large amounts of detailed and consolidated data from different dimensions. • Analytical Processing: • Drill-up (Consolidation)– ability to move from detailed data to aggregated data • Profit by Product >>> Product Line >>> Division • Drill-down – ability to move from summary/general to lower/specific levels of detail • Revenue by Year >>> Quarter >>>>Week >>>Day • Slice and Dice– ability to look across dimensions • Sales by Region Sales • Profit and Revelers by Product Line

  49. REGION CUSTOMER • Slicing a data cube
