Data Tree

The Data tree presents a dimensional view of your data, organized into dimensions, hierarchies, levels, and measures.

Page 7: COGNOS 8 - Analysis Studio

COGNOS BI TOOLS BI Practice

The Analysis Items Tab The Analysis Items tab contains items created in the analysis, such as custom

sets and named sets

Page 8: COGNOS 8 - Analysis Studio

COGNOS BI TOOLS BI Practice

The Information Pane The Information pane shows the name, level , attributes, and aggregation

associated with the selected item in the data tree

• Possible aggregation types for measures are sum, count, count distinct, count nonzero, and none.

• Possible aggregation types for other items are rollup and computed.

Page 9: COGNOS 8 - Analysis Studio

COGNOS BI TOOLS BI Practice

The Properties Pane The Properties pane provides a comprehensive view of the cross tab or

selected set in the work area.

• Specify the number of items to show

• Create a user-defined filter

• Sort data

• Unhide data

Page 10: COGNOS 8 - Analysis Studio

COGNOS BI TOOLS BI Practice

The Overview AreaPlace to quickly explore and change the contents of the work area.

The overview area shows

• Applied filters and sorting.

• Manipulate rows and columns

• Drill up or down

• Context

Page 11: COGNOS 8 - Analysis Studio

COGNOS BI TOOLS BI Practice

The Overview Area

Rows and Columns:Each box in the Rows area and Columns area represents one or more

sets in the cross tab.

Stacked sets -- appear as a single box labeled Combination.

Selection-based set -- appears as a box with (list) appended to the label.

Context:

The context you specify applies as a whole to the work area.

For example, drag Sales Territory from the Insertable Objects pane to the context area. When you click a specific territory from the list, the values in the cross tab change to represent data for that territory

What is New (Analysis Studio)

Details 

Enhanced user interface  The enhanced Analysis Studio user interface , comprised of the data tree, a crosstab, and the overview

area, to manipulate data from large OLAP sources.   Easier comparative

analysis  • The ability to select multiple members from anywhere in a hierarchy

• The ability to insert multiple sets of data in the rows or columns

Filters  • Enhanced Top or Bottom filters

• Create multiple filter rules by combining filters

Calculations • New summary calculations, such as average, count, and variance

FiltersZero Suppress Filter

It provides a quick way to exclude rows or columns that don’t have any values

• Can be applied to rows, columns or both

• Options to suppress nulls, zeros or both

See Settings > Zero Suppress

Exclude -Option

Exclude:- When you exclude items, you exclude the value from the Subtotal (included) subtotal, as well as hide the row or column from view.

Its value is now rolled up into the Subtotal (excluded) subtotal.

Sets

Sets are the basic building block of the cross tabs in Analysis Studio.

Set is a group of related items, based on a single integrity

The following sets are available in Analysis Studio

Detail-based Set Level-based Set

Selection Based Set Measure Set

Custom Set Pre-define Set

Stacked Set

Page 20: COGNOS 8 - Analysis Studio

Set – Description

Set   Description 

Detail-based set 

A collection of data based on a selected item and all its immediate details. For example, you can have a set of data named years that includes quarters as details. 

Selection-

based set  A collection of individual items that you have explicitly selected. The items or members may be selected from one or more levels from the same hierarchy. 

Level-based set 

A set based on a single level

Stacked set  Also known as a union set.

Two or more independent sets adjacent to each other in a cross tab

Page 21: COGNOS 8 - Analysis Studio

Set – Description

Set   Description 

Measure set  Measure sets are comprised of one or more measures.

In nested sets, measure sets may be placed on the inside of either the rows or the columns, but not both. 

Custom set  A collection of data defined in Analysis Studio that can be saved and reused in the same analysis

Predefined Set  A set of members defined inside an OLAP data source as a list or by an expression.

A predefined set is also known as a named set in Microsoft SQL Server Analysis Services.

Basic Crosstab Layouts The following layouts are available for analysis.

Basic Cross tab Layouts

Layout  Description  Illustration 

Basic  This layout contains one set of rows and one set of columns. 

 

Nested This layout contains sets nested either along the rows, the columns, or both.

Cross tab Layouts

Basic Cross tab Layouts

Layout  Description  Illustration 

Stacked

This layout contains two or more sets arranged one above another on the rows, side-by-side on the columns, or both.  .

Basic Cross tab Layouts

Layout  Description  Illustration 

Asymmetric 

This layout contains both nested and stacked sets. Many combinations are possible. 

 

Page 25: COGNOS 8 - Analysis Studio

COGNOS BI TOOLS BI Practice

Asymmetrical Cross tab Layouts Nested Rows : Insert data above or below a selected set in nested rows.

• For example, select set 2, right-click the desired data in the data tree, and click Insert, Below Selected Item to create set 3.

Nested Columns : This example uses nested columns.

• Select set 1 in the columns, right-click the desired data in the data tree, and click Insert, After Selected Item to create set 3.

Stacked Sets: Insert data before or after a selected set in a stacked set.

• For example, select set 1, right-click the desired data in the data tree, and click Insert, After Selected Item to create set 3.

Selection-Based Sets:

• Replace a selection-based set with one or more items from the same hierarchy to create a new set instead of appending the selected items to the existing set.

Exploring Data

Explore your data to look for significant comparisons and correlations.

The ways of exploring data are

• Drilling down and up

• Going to another report or package

• Showing values as percentages

• Sorting values

• Showing values graphically in charts

Page 28: COGNOS 8 - Analysis Studio

COGNOS BI TOOLS BI Practice

Limiting Data Various ways to filter out unnecessary data are,

• Filter values to show only the data you want to view

• Exclude items to eliminate unwanted information

• Apply a top or bottom rule, when analyzing a large amount of data

• Create a user-defined filter to limit the items shown to those that meet a specific criteria

• Remove rows or columns containing only missing value

Page 29: COGNOS 8 - Analysis Studio

COGNOS BI TOOLS BI Practice

The Technique of quickly focus on one or more items for particular view of the data is known as filtering using context.

Example,

You have a cross tab showing products in the rows and revenue for different quarters in the columns. To change the context to Asia, you drag Asia from the data tree to the Context section of the overview area. The cross tab then shows

only the values for Asia.

Calculations

Objects selected  Available calculations 

A single row or column 

Rank, show values as a percentage of the total, round or round down values, and show absolute values 

Two rows or columns 

Arithmetic and percentage calculations 

Three or more rows or columns 

Aggregate calculations, such as sum, average, maximum, and minimum 

A Set  All calculations in the Calculate dialog box 

The calculations available depend on how many columns or rows you select before you click Calculate.
