PowerPivot DAX
3
Data Analysis Expressions (DAX)
Simple Excel-style formulas
Define new fields in the PivotTable field list
Enable Excel users to perform powerful data
analysis using the skills they already have
Has elements of MDX but does not replace
MDX
4
4
Data Analysis Expressions (DAX)
No notion of addressing individual cells or ranges
DAX functions refer to columns in the data
Sample DAX expression
= [First Name] &“ ”& [Last Name]
=SUM(Sales[Amount])
=RELATED (Product[Cost])
5
Means:
String concatenation just like Excel
SUM function takes a column name
instead of a range of cells
new RELATED function follows
relationship between tables
5
DAX Aggregation Functions
DAX implements aggregation functions from Excel including SUM,
AVERAGE, MIN, MAX, COUNT, but instead of taking multiple
arguments (a list of ranges,) they take a reference to a column
DAX also adds some new aggregation functions which aggregate
any expression over the rows of a table
SUMX
(Table, Expression)
AVERAGEX
(Table, Expression)
COUNTAX
(Table, Expression)
MINX
MAXX

PPS in SharePoint 2010
PerformancePoint Services in SharePoint 2010
improve over PerformancePoint Server 2007:
SharePoint does all security, management, backup,
respository of dashboard
Decomposition Tree
KPI Details
Scorecard drilldown, dynamic hierarchies, calculated KPIs
Dynamic, up-to-date filters for time intelligence
SharePoint Dashboard Designer is smoother
Better accessibility
Analytic charts with value filtering and server-based
conditional formatting

Algorithm
Description
Decision Trees
Finds the odds of an outcome based on values in a training set
Association Rules
Identifies relationships between cases
Clustering
Classifies cases into distinctive groups based on any attribute sets
Naïve Bayes
Clearly shows the differences in a particular variable for various data elements
Sequence
Clustering
Groups or clusters data based on a sequence of previous events
Time Series
Analyzes and forecasts time-based data combining the powerof ARTXP (developed by
Microsoft Research) for short-term predictionswith ARIMA (in SQL 2008) for long-term
accuracy.
Neural Nets
Seeks to uncover non-intuitive relationships in data
Linear Regression
Determines the relationship between columns in order to predict an outcome
Logistic
Regression
Determines the relationship between columns in order to evaluate the probability that a
column will contain a specific state

Summary
Advanced self-service analysis requires a rich
expression language: DAX
Team, and organisational BI dashboards and
scorecards are easy to build using SharePoint
2010
Data Mining enables advanced pattern
(correlation) discovery in your data
