3. Objectives ▪ Define Business Intelligence, OLAP & Visualization ▪ Explain the Efficiency principle of Spreadsheet Design ▪ Demonstrate Excel features that help produce business intelligence

4. Pandora Internet Radio ▪ Recommender Software Music Genome Project Arrangement Beat Harmony Lyrics Melody Rhythm Tempo Voice

5. Business Intelligence (BI) ▪ software that searches vast amounts of data to derive information for improved decision making

6. Logical Calculations ▪ IF ▪ VLOOKUP

7. ▪ IF function displays one of two possible values depending on the outcome of a logical test ▪ Logical Test compares two things ▪ If the Logical Test equates to TRUE, the cell is filled with the True Value. ▪ If the Logical Test equates to FALSE, the cell is filled with the False Value. IF Function http://www.lacoste.pamplin.vt.edu/web1504/resources/video/ss.html

8. ▪ Use the IF function to assign the label of easy or hard based on the hours. If a course requires more than 3 hours of study time per week, we will label it HARD. Three or less hours of study is labeled EASY. IF Function Example

9. ▪ What cell is used for the logical test? ▪ What is the logical test? ▪ What is the true value? False value? IF Function Example 3

10. ▪ LOOKUP functions display one of MANY possible values depending on the outcome of a logical test. ▪ Often used to translate one value into another value. ▪ Requires a lookup table. ▪ Lookup Value is compared to Lookup Table ▪ Can find Exact Match (false) or next closest value (true) VLOOKUP Function http://www.lacoste.pamplin.vt.edu/web1504/resources/video/ss.html

11. ▪ First column must be used for logical test. ▪ First column must contain a value, not a range of values. ▪ First column should be in ascending order. Lookup Table Rules

12. Lookup Directory Example ▪ Find the extension for a given name in the directory.

13. Lookup Table for Directory Example

14. Lookup Directory Example Solution 1.F1 is compared to first column of lookup table. 2.Extension from Column 2 is displayed for match. 3.False means an exact match must be found.

15. Spreadsheet Design: Efficiency ▪ All calculations, including comparisons, should be done by the spreadsheet.

16. BI – Data Visualization On-Line Analytical Processing ▪ Drill-Down ▪ Consolidation ▪ Slicing and Dicing
