Cognos powerplay

The world's best-selling OLAP software lets users
explore volumes of data with sub-second
response.
•It enables users to explore large volumes of
summarized data with sub-second response times in
a Web, Windows, or Excel environment.
•With Cognos PowerPlay, users at any business or
technical skill level in a company can perform their
own multidimensional analysis, create reports, and
share them for better decision-making.

Introduction to Cognos Powerplay

•Cognos PowerPlay draws information from relational
databases to model and build PowerCubes ("Cubes").
•Cubes are data sets that can contain tens of millions of
consolidated rows of data and hundreds of thousands
of categories (members).
•Business rules and calculations (for example,
percentage growth and market share change) can be
built right into them, and time series analysis is
delivered automatically.
•Cubes and reports can be deployed to Web clients, or
to Windows and Excel clients, all using the same
application server.


Cognos PowerPlay provides both a multidimensional
data store and a feature rich end-user experience.
Its multi-server, load-balanced architecture is easy to
install and manage, and it scales to thousands of users.

• On Line Analytical Processing.
• What is Business Intelligence?
• What are Measures?
• What is a Dimension?
• Multidimensional Analysis.

OnLine Analytical Processing
• What is OLAP?

– On Line No piles of paper.
– Analytical Establish patterns
– Processing Data-based

• On-line Analytical Processing (OLAP) is a category of
software technology that enables analysts, managers
and executives to gain insight into data through fast,
consistent, interactive access to a wide variety possible
views of information that has been transformed from
raw data to reflect the real dimensionality of the
enterprise as understood by the user.


What is Business Intelligence?

• Business Intelligence (BI) is:
– the use of corporate data to support decision-
making
– the ability to explore and analyze data to reveal
trends within a business.
• How does it happen?
Raw Data

Organized Information

Better Business Decisions

What are Measures

• The numeric data that is collected and
stored by your organization are the
measures you will use to evaluate your
business.
• These are also termed as Facts.

Example:-
Cost
Quantity sold
Units on-hand
Hours per Job
Number of calls


What is a Dimension?
• A dimension:
– Dimensions represent those data element that
would be used for analyzing the Facts.
– depends on data availability and on the key
performance indicators of the business

What Are PowerCubes?

• PowerCubes:
• are created by Transformer
• organize data into selected business perspectives
or dimensions.

How Does PowerPlay Deliver BI?
• Powerplay Transformer combines all of the data into a
summarized format called a PowerCube.
• The PowerCube structures data into a multi-
dimensional format.
• Every decision-maker uses data organized into various
reports

by Customer Type


PowerPlay Components

• PowerPlay includes the following components:

Transformer defines the PowerPlay application
and creates the PowerCube. (*.MDC)

PowerPlay accesses the PowerCube to give you
the ability to explore your business information
quickly and to build powerful customized reports.

Dimension Line

• The Dimension Line:
– represents the various aspects of your business
– contains a series of folders of all the available
dimensions and measures.


Dimension Viewer

 Use the Dimension Viewer to see a hierarchical
organization of dimensions and
categories in your cube.

Dimension
= Locations

Level 1 = states
Category = CA
Toolbox
Level 2 = cities
Category = San Diego


Levels and Categories
• Data is organized into dimensions and stored in a
hierarchy of levels.
• A category is a data item that exists in a level.

Locations Dimension
Level = Region Level = Country
Belgium ...
Europe Germany ...
France ...

Categories ...
Far East

Americas ...


Explorer Report

• To explore and analyze your data, you can:
– create a new report from a cube
– open a .ppr file.
• The default display contains:
– the first two dimensions in the rows and columns
– the values for the first measure.


Reporter Report

A Reporter report provides you with:
– flexibility over the content of your report
– a blank report to which you add the categories you want
to analyze.


Tools for Data Investigation.

• Various Tools For Investigation
• Additional ways of Investigating the Data

Various Tools For Investigation

• Drill-Down and Drill-Up.
– Drilling down or up is a specific analytical technique
whereby the user navigates among levels of data
• Slice & Dice.
Slice and dice allows you to change and arrange
dimensions in a report, which provides a different perspective
on your data.
• Changing Displays.
By changing the display you can see trends and relationships in
a graphic.

• You can slice and dice by dragging a new dimension
folder into the display.

Various Tools For Investigation

• Using Alternative Drill-Downs.
• Special Categories.
• Replace Rows and Columns.
• Swap Rows and Columns.
• Explanation Window.


Alternate Drill Down and Drill Up Paths

• Alternate drill paths:
– provide you with additional

Using Special Categories

• Special categories:
– are used to compare trends
– provide an alternate organizations of the data.

Analyzing Data

• Rank and sort data
• Filter data using different methods
• Add layers
• Use measures and multiple measures.
• Nesting and Formatting.
• Using Charts.

Rank Data
• Rank categories by their value in a specific row or
column.
• See interesting trends like top selling Tents.
• By default:
– ranked data is sorted
– data is re-ranked as you drill or slice and dice.


Sort Data
Sorting data:
• arranges categories in alphabetical or numeric order
• finds products or customers quickly and easily.

Alphabetical

Numeric


Filter Data Using the Dimension Line
• Filtering creates focused reports that show you the
exact level of information desired in each dimension.
• You can filter your report to focus on a particular
location.
• The Dimension Line displays the filters in use.


Filter Data Using the Dimension Viewer
• You can filter data by clicking the Filter button.
• The Dimension Viewer displays the hierarchical position
of the filtered category.


Layer Data

• Add layers to a report as a third set of
dimension categories.
• Drag a dimension folder to the Layer target.

Locations Layer 4 of 4
North America Layer 3 of 4
Europe Layer 2 of 4
Far East Layer 1 of 4


Suppress Zeros
• Remove any zero value categories from the report to
focus only on positive outcomes.

Suppress zeros, rows, and columns


Show Values as Percentages

• Display the values in your report as a percentage of
various totals.

Percentage
of Row Total


Change Measures
• Use the Measures folder to change the key performance
indicator of a report.
• By default, the values in a new report are based on the
first measure in the measure list.


Multiple Measures
• Display multiple measures to examine differences
between them.
• Show multiple measures in the rows, columns, or
layers.


What is Nesting ?
• Nesting is the introduction of another level to:
– provide additional information within the crosstab
– increase the perspective of your exploration.


Create a Nested Crosstab
• Drop zones are located in the crosstab label areas of
both rows and columns.

Inserting a first-level column nested category

Select an item and
then drag

Select Nested Categories

 When you select a nested category, all occurrences of that
category within the report are selected.


Layout Options

 PowerPlay gives you three layout options to choose from:
Standard

Indented 1

Indented 2


Add Titles, Headers, and Footers

 To customize titles, headers, and footers:
 insert an item from the Insert menu

 cut and paste to and from the clipboard

 apply various font styles to text.

What are Standard Reports?

• Standard Reports will be used on a recurring basis and
provide up-to-date cube data.


What are Subset Definitions?

• With a subset
definition, you
can view up-to-
date cube data in
a Reporter
report.


Creating a Subset From a Subset Definition

• A subset definition is added to a report the same way
as a category or dimension is added.

Changing a Non-Standard to a Standard Report

• Because standard reports are created with subsets, any
changes to the categories will be updated.
