2. Abstract
Excel 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.
