AbstractExcel 2010 provides a world‐class platform for enterprise decision making. This presentation introduces the decision‐making ability possible with the free Excel add‐ins for PowerPivot and SQL Server Data Mining. The data mining is a service hosted in Microsoft's Analysis Services, but the Excel add‐in exposes the enterprise‐strength server technology to analysts and executives. This talk introduces some functions from the "Analyze" and "Data Mining" tabs, including data mining model creation from Excel data. Having seen this presentation some had thought it was all Excel since the functions seem so seamless. The Excel interface provides a familiar way for professionals to make actionable decisions.
