  1. Intro to PowerPivot Stockholm, Jan 27, 2010 Rob Collie, Sr. Program Mgr, PowerPivot Event sponsored by

  2. “The funny thing about Europe”

  3. Agenda • Why PowerPivot? • Demos! • Why SharePoint? • Demos!

  4. Why PowerPivot? • Money • Biz logic bottleneck • Time • Cost • Lack of agility • Embrace and improve Excel • Manage and assist, not fight • Supplement centralized BI

  5. TempMashup Demo • Loading Data • Simple Pivot • Mashup with Internet data • Calc columns and relationships • DAX Measures

  6. DAX Measure Golden Rules • Home Table = Fact Table • Wherever the column to be aggregated lives • No naked columns! • Sum([Quantity]), never just [Quantity] • Measures themselves are also ok • Calculations happen against the TABLES • Ex: Sum of a column in a PowerPivot table • NOT a sum of PivotTable cells • NOT a navigation of dimensional space • Two Phases: Filter, then Aggregate • During Filter, think “Cell-by-Cell” • Filters flow from One to Many, NEVER vice versa

  7. Movie Explaining the Golden Rules • Pretty sure I lost people here • Probably (hopefully) clearer here: • http://bit.ly/ambRrv • http://bit.ly/bv7tBo

  8. The Great Football Project • Real Project! (2006) • Professional BI consultant • $50k, 3 months • Top-notch SSIS/SSAS pro • Professional data! • $100k license to STATS Inc. • “Professional” only meant “Expensive”

  9. Schema Diagram

  10. Schema Diagram, cont’d

  11. Dimension Tables

  12. Fact Tables

  13. Football Demo #1: Measures

  14. The CALCULATE() Function • Your new best friend • Like SUMIF(), modernized =CALCULATE(<Aggregation>,<filter1>,<filter2>,…)

  15. Football Demo #2: Cube Formulas

  16. Why SharePoint? • XL Pro • (Practical)Security • No “Save As” hijacking • Guaranteed deployment of updates • Autorefresh • “Professionalized” results • DB Pro / IT • Transparency • Usage tracking • Focused point of engagement

  17. SharePoint Demos • Gallery • Autorefresh • Usage dashboard

  18. Bonus Slides!

  19. DB Pro/XL Pro Partnership • DB Proprovides clean, complete, reliable data • XL Pro provides biz logic and reports • Deputized XL users as ambassadors • Provide focused feedback on DW • “If we had a table like this, we could do X” • DB Pro can proactively offer additional support • “I see you are using Y as a data source” • “Can we help insulate against outages?” • “I better not rename that db after all”

  20. More DAX Functions You Should Know About • ALL() • Clears pivot filtering from specified fields • Clears filters for measure calculation, not visually • Useful for % of total calcs • SUM([Sales]) / CALCULATE(Sum([Sales]),All([Products]) • Time Series Functions • 39 Functions • PARALLELPERIOD(), TOTALMTD(), PREVIOUSDAY()…

  21. Cube “Side Effect” • PowerPivotdb engine IS Analysis Services • PowerPivot Workbooks are exposed as cubes • ONLY when published to SharePoint • Query API (OLAP) is 100% unchanged • Must use updated provider (OLEDB, ADOMD) • Connect via workbook URL • Subset of cube concepts supported • No true hiearachies for instance

  22. My Advice for BI Pros: Learn About SharePoint • All MS BI now centered on SharePoint • This was bottom up process, not an executive edict… • …which makes it a much more significant trend • …and it’s also why we havenot said this as loudly as I’d like • Complete BI solutions will now often involve: • SharePoint Install/Config • Integration between BI apps • BI integration into existing SharePoint solutions • Custom web part development (or integration) • SharePoint authentication and security • SharePoint pros more aware of BI than I had expected
