Demo with Live data
SQL Server Power Pivot for Excel
• Manages compressed storage of, and extremely fast querying
and reporting from, large volumes of related tabular data
• Data can be loaded from a variety of data sources
• Leverages familiar Excel features
• Uses Data Analysis Expressions (DAX) for sophisticated
transformation of data
• Supports publication of PowerPivot reports to SharePoint
• Functionality is delivered by two add-ins:
• SQL Server PowerPivot for Excel add-in
• SQL Server PowerPivot for SharePoint add-in
PowerPiavot for Excel 2010
• Ad-hoc large data
analysis
• In-memory
Database
• Fast, compressed,

• Data integration
• Data Analysis

Who Is the PowerPivot Audience?
• Excel users who know how to structure and work with
relational data in workbooks
• SharePoint users who use team sites and document
management features
• Database and IT professionals who:
− Want to delegate business data development tasks to those
who need the data most
− Need to retain sufficient control so that data can be
secured, monitored, reproduced, and archived
•demo
Mashing-Up PowerPivot Data
SQL Server PowerPivot for Excel Add-in
• Client add-in that extends Excel 2010 to support extremely
large data sets
− Achieved with a client-side version of Analysis Services,
known as the VertiPaq processor
• A separate PowerPivot Window is used to load, explore,
relate, and enrich data with calculations
• Imports and relates data from corporate, local, and ad hoc
data stores
• Results in a new data source embedded in the Excel
workbook that becomes the basis for interactive reports

What’s New in PowerPivot for SQL 2012
Diagrams
Calculated Measures
KPIs
Hierarchies
Perspectives
Multiple Relationships
Integration with SSAS Tabular Mode
PowerPivot for Excel is still free!
DAX
• DAX is a calculation language for PowerPivot
• It is a multidimensional calculation language like MDX, but the
design goals were:
• Make it easy to do common calculations (easier than MDX)
• Make it easy to use for Excel power users, hence the Excelbased syntax
• DAX expressions are limited to a single (though often very long)
line of code
DAX: New Features in SQL 2012
• DistinctCount
• Filter
• Evaluate
• IsSubTotal
• Summarize
• CrossJoin
• AddColumns
• TopN
• Switch
• Row
• Order By
• DateAdd
• Start At
• HasOneValue
• ROLLUP
• Search

Known Issues
• Cannot Use a Calculated Column to Mark a Table as a Date Table
• PowerPivot Stops Responding When You Copy a Large Amount of Data to the Clipboard
(Workaround: Copy only small data sets in PowerPivot)
• Duplicate Linked Tables are created in Diagram View (Workaround: Make sure PowerPivot is in
Data View when you create linked tables)
• A Hierarchy Appears as a Flat List if it Is Used as a Report Filter (Workaround: Do not rename
the hierarchy on the report level when you add a hierarchy as a Report Filter)
• PowerPivot Management Dashboard Does Not Load on a Domain Controller
• PowerPivot Management Dashboard's Bubble Chart Control Might Not Work
• F1 Help Does Not Show Localized Content for Chinese Languages
• PowerPivot Fails to Open the Import Wizard for .atomsvc Files Larger than 64Kb
• Filtering Members from Different Levels of a Hierarchy Causes an Error

Tabular Models over Power Pivot Models
Area
Pro Features
Scalability
Power Pivot has a 2 GB limit for the size of the Excel file. Tabular models do not have a hard
upper size limit.
Tabular models have partitions, which are used to manage processing of large data
volumes. Power Pivot does not.
Securability
Manageability
Tabular models support DirectQuery. You can consider DirectQuery almost as a scaling
feature as it allows you to avoid processing large data volumes altogether. Power Pivot only
queries the VertiPaq cache
Tabular models can be secured using row security. Dynamic security is also supported.
Power Pivot does not support row security or dynamic security. Security for a workbook is
just a binary choice – either a user can read a workbook or she can’t.
SSMS has the backup, restore, attach, detach, delete, and synchronize features that you
would expect. You can also script out from SSMS, browse your cube, and query your cube
using MDX. All of these features work the same for multidimensional and tabular models.
Processing Options for Tabular Model
Processing Option
Description
Process Add
Adds new rows to a partition. Any affected calculated columns, relationships, user
hierarchies, or internal engine structures (except table dictionaries) are
recalculated.
Drops all the data in a database, table, or partition.
Loads data into a partition or table.
Process Clear
Process Data
Process Default
Process Defrag
Process Full
Process Recalc
Loads data into unprocessed partitions or tables. Any affected calculated columns,
relationships, user hierarchies, or internal engine structures (except table
dictionaries) are recalculated.
Optimizes the table dictionary (an internal engine structure) for a given table or
for all tables in the database. This operation removes all dictionary entries that no
longer exist in the data set and rebuilds the partition data based on the new
dictionaries.
Loads data into all selected partitions or tables. Any affected calculated columns,
relationships, user hierarchies, or internal engine structures (except table
dictionaries) are recalculated.
For all tables in the database, recalculates calculated columns, rebuilds
relationships. rebuilds user hierarchies, and rebuilds other internal engine
structures. Table dictionaries are not affected.
Query Modes in Tabular Model
Query Mode
Description
Limitation
DirectQuery
This setting specifies all queries
to the model should use the
relational data source only
• Custom security
implementation may not work
(It throws an exception and
stops working)
• Calculated columns are not
allowed
In-Memory
This setting specifies queries
should be answered by using the
cache only
SSIS with tabular models
Analysis Services Processing Task
Only some of the processing options are appropriate for tabular models.
Process Full, Process Default, Process Data, and Process Clear are fine
processing choices for tabular models. Process Indexes, not so much.
Processing options that apply only to tabular models do not appear in this
processing task. If you want to Process Recalc (and you do want to do this
after a Process Add, Process Clear, or Process Data), you have to use the
Execute DDL task instead.
Analysis Services Execute DDL Task
This task is fully supported and works great with tabular models.
