Power Pivot Overview

What is new in PowerPivot/ BIDS

Power View

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, interactive

• Data integration• Data Analysis

Expressions (DAX)

• No IT Dept support needed

PowerPivot and Data Integration

Self-service acquisition and mash-up of data from any source• Databases (any)• Reports• Cubes• Data Feeds• Azure DataMarket

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

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 Excel-

based syntax

• DAX expressions are limited to a single (though often very long)

line of code

DAX: New Features in SQL 2012

• DistinctCount

• Evaluate

• Summarize

• AddColumns

• Switch

• Order By

• Start At

• ROLLUP

• Filter

• IsSubTotal

• CrossJoin

• TopN

• Row

• DateAdd

• HasOneValue

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 ModelsArea 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.

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

Securability 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.

Manageability 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.

Process Clear Drops all the data in a database, table, or partition.Process Data Loads data into a partition or table.

Process Default Loads data into unprocessed partitions or tables. Any affected calculated columns, relationships, user hierarchies, or internal engine structures (except table dictionaries) are recalculated.

Process Defrag 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.

Process Full Loads data into all selected partitions or tables. Any affected calculated columns, relationships, user hierarchies, or internal engine structures (except table dictionaries) are recalculated.

Process Recalc 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 ModelQuery 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.
