An Overview of OracleBI
Discoverer Plus
The earlier versions of Discoverer supported querying
only relational data sources. The current version of Discoverer supports querying
both relational and multidimensional OLAP data sources. Discoverer Plus OLAP
is used to query multidimensional OLAP data sources, whereas Discoverer Plus
Relational is used to query the relational data sources. This lesson primarily
covers the new features of Discoverer Plus Relational.Also,
note that in this OBE, the terms Discoverer
Plus and Discoverer
Plus Relational are used interchangeably.
Using Discoverer Plus Relational, you can create, modify,
and analyze reports. The current version of Discoverer Plus has a new look and
feel, and an improved and interactive user interface with many new features. The new
interface enables the BI analysts to create reports interactively with a few clicks. The new or enhanced features of Discoverer Plus include improved
wizards, interactive item navigators, enhanced graph features, enhanced formatting
features, cascading parameters, enhanced printing and export features, and so on.
In this lesson, you learn how to
use the new features of OracleBI Discoverer Plus to create and modify reports
interactively by using a relational data source
and sample workbooks.
This topic demonstrates the above mentioned new
features of Discoverer Plus. To understand these features, you will connect
to Discoverer Plus, open an existing sample workbook, and also create a simple
new worksheet by using the new Worksheet Wizard.
In addition to the public and private connections
supported in the earlier versions of Discoverer, you can also connect to Discoverer
Plus by providing the login details directly without having to create a connection.
Note: Now,
you can access both OLAP and relational data sources from the same connections
page of OracleBI Discoverer.
1.
In the Web browser, enter the URL for Discoverer
Plus. This will display the Connect to OracleBI
Discoverer screen. The URL looks like the one given below:
http://<hostname>:<port>/discoverer/plus
2.
Enter the login credentials for the
bi_user in the Connect Directly section.
Enter the username and password, and the database connect string as shown.
Enter the EUL name in uppercase (BI_USER), and click Go. This
will connect you to Discoverer Plus.
Note: Alternately, you can choose from
the list of predefined connections. You can also create a private connection
by using the login credentials for the database that you want to connect
to. Also, note that when you have a stand-alone BI installation, which is
not associated with the infrastructure database of the Oracle Application
Server, you will see only the Connect Directly
option, not the connections. To associate the BI installation with
the infrastructure database, contact the middle-tier administrator.
In this exercise you'll open an existing sample
workbook. Observe the enhanced UI, which includes options such as search for
workbook names, and so on. Note: Open the same sample workbook as mentioned

by dragging this item to the page axis. Alternately, you can select the appropriate
option to pivot this item from the shortcut menu as shown in the image
below.
Similarly, move the Region item to
place it before the Sales Revenue SUM
item. After pivoting Year to the page axis, and placing Region before
Sales Revenue SUM, this is how the worksheet will look:
You can see that the worksheet items are arranged better now, and also
that pivoting can be done interactively.
3 .
Add suitable data formats to the items in
the worksheet. For example, you can apply currency
formats to Sales Revenue SUM
and Profit SUM items.
Note: You can apply the appropriate currency format
by selecting the Format Data option from the shortcut menu. In the Format
Data Dialog box, select appropriate currency options as shown below.
After applying these formats, the worksheet will look like this:
Changing Gridline Colors from

icon (highlighted in the image below). Alternately, you can drag the item
to be added from the Available Items pane, and drop it on the worksheet.
3 .
The worksheet with the newly added item is shown below.
By default new items are added at the end. However, in the worksheet below,
note that Prod
Category is placed (pivoted) before Sales
Revenue SUM.
Note: Similarly , you
can also remove the items from the worksheet interactively.
Adding a graph to a worksheet helps end users to easily see
the trends and abnormalities in the data. Discoverer Plus supports many graph
types and subtypes (150+ types). In addition, Discoverer Plus has many new features
such as graph styles, fitline options, and drill from graphs. Choosing
the right type and style of graph, and the ability to drill from the graph helps
to improve visualization to analyze data trends. So, these features will not
only improve the look and feel of the graphs, but also improve data visualization.
In this exercise, you will add a graph to the worksheet,
select appropriate style and fitline options for the graph, and you will also
drill from the graph to visualize data better.
To add a graph to the worksheet, perform the following steps:
1.
Before proceeding with
this exercise, interchange the positions of Region and Year items. (That
is, move Region to the page axis, and Year to top axis). The worksheet
now looks like this:
Select the Edit > Worksheet Layout menu option. Note:You can alternately
select Edit > Worksheet and open the Worksheet Layout page.
2.
Select the option to
add a graph to the worksheet, and select the option to display the graph
below the worksheet. Click OK.
3.
The worksheet will now look like the image
below. Edit the graph type and subtypes to improve the visualization.
Right-click the graph in the worksheet, and select the Edit
Graph option from the shortcut menu. Note: Observe that a simple Bar graph
is added to the worksheet. However, the graph type and subtypes added
may differ based on the last graph added in the workbook.
You can also edit a graph by clicking the Edit Graph icon
on the toolbar.
4.
Open the Type
tab. Select Bar as the graph type, Split Dual-Y
Bar as the graph subtype, and click OK.
The graph in the worksheet will now appear like this:
Modifying the Graph
Style and Using Fitline Options
You can further improve the look and feel of the graph by
using new Graph Styles and Fitline options provided in the current version of
Discoverer Plus.
1.
Click the Edit Graph icon on the toolbar,
and go to the Styletab.
From the Style drop-down list, select
Regatta as the option and also select
the option to display 3D Effect in the
graph.
2.
A sample of the graph style that you have
selected is reflected in the page. Click OK.
After applying this graph style, this is how the worksheet looks like:
3.
To add Fitline options, click the Edit Graph icon
and open the Plot Area tab. Select
Linear as the Fitline
option for Profit SUM and
Sales Revenue SUM. Click OK.
Note:This option can be found in the
table under the section Select options for
the series displayed in your graph.
The graph in the worksheet now shows the Fitline
option added. Note that though sales revenues were raising, profits do
not show this trend.
Note: You can also change
the series colors from the Plot Area tab, as shown in the screen below:
Now Discoverer enables you to perform drills using graphs.
For example, you can drill down from Year to Quarter from the graph to view
Quarterly information. Follow the steps listed below to explore this feature.
1.
In the graph, click the legend for the
year 2001 to view the quarterly information.
2.
The worksheet and the graph now display quarterly
information. Change the Fitline option for both Sales Revenue SUM and
Profit SUM series to Exponential. You can see that the Profits and Sales
Revenues have started increasing exponentially in the year 2001.
You can intuitively add a calculation to the worksheet. For
example, you want to see the profit margins for all years by region. Follow
the steps given below to add a calculation named My Profit Margin.
1.
You can click the icon for New
Calculation (highlighted in the image). Alternately, open the
Calculations page, right-click the My Calculations node, and
select New Calculation option.
2.
Enter My Profit
Margin as the name for the calculation, and add a formula to calculate
profit margin (Profit SUM/ Sales Revenue SUM) in the Calculation field.
Click OK.
The Calculation will be added automatically to the worksheet as shown
below. You can also see this calculation added to the My Calculations
node and also in the Selected Items pane.
Note that the graph type used here is
Line with a subtype Dual-Y Stacked Line.
3.
Change the data format for My Profit Margin to represent
it as a percentage, without decimals.
Now the worksheet looks like this:
Note: To save
the changes that you are making to the worksheet, you can save
the workbook. Also, if you want to save the changes as a separate worksheet
in the same workbook, then you can duplicate the worksheet, and give
it an appropriate name before saving the workbook. For example, you can
name the above worksheet as Regional Profit Margins By Year. Duplicating
a worksheet can be done from the Edit > Duplicate
Worksheet menu option as shown below:
Discoverer Plus has improved features to sort and format
the data in the worksheets. While creating the worksheets, you can choose to
use the correct formats and sorts in the worksheets, which improves the visibility
of the data for the end users. While earlier versions supported sorting, in
the current version of Discoverer Plus, you can format the data better by using
page break and line break options for group sorted items. Also,
you can apply conditional and stoplight formats to the items in a worksheet.
You can also add Title and/or Text Area to the worksheets too.
In this exercise you will perform the following tasks to know
about these new features:
The image below displays a tabular worksheet,
with Region pivoted to the top axis. This worksheet displays sales, profits,
and profit margins for all the regions and years. To add a group sort
on year (or in general, any sort on an item), you need just a single click.
Select the item Year and click the group
sort icon on the toolbar.
You can also do the same from the shortcut menu of the item.
(Note that the worksheet layout is edited not to display page items and
graph; and also font sizes for the items are changed.)
The worksheet looks like this after applying a group sort on
Year:
2.
To apply line breaks or page breaks right-click Year and select Format
Data option.
3.
Observe the tabs, and open the Breaks
tab. Select to insert a line break at each change of value, select the
line width as 3, and select a color for the line break as shown in the
image below. Click OK.
Now the worksheet looks like this:
Note: You can select from custom colors,
or edit the colors to add your own combinations of colors.
Similarly, you can define page breaks too. Also,
note that page breaks can be applied only to tabular worksheets and not
crosstabs.
4.
Similarly, add sorts on Sales
Revenue SUM and Profit SUM to
display these items in descending order. Hint: Use the sort icon
on the toolbar. Also, you can define sorts from Tools > Sort menu option.
5 .
Now the worksheet looks as shown in the image below. Observe
that Americas and Europe Regions are doing well in terms of the sales
revenues and profits. You can also see that profit margins declined in
the year 2000, and started rising again in the year 2001.
In the current version of Discoverer Plus, you
can define conditional and stoplight formats. These new features enable you
to apply formats to the data in the worksheets, based on the conditions or thresholds
defined. Applying conditional formatting to items in the worksheet
enables you to easily identify exception data. When applied on an item, the
item is formatted as specified in the condition. Stoplight formatting
enables you to quickly and easily define thresholds that automatically format
worksheet data to indicate if a particular value falls into the Desirable, Acceptable,
or Unacceptable ranges established by the thresholds defined.
Using these formats with correct thresholds improves
the visibility and readability of the data, and makes the process of analyzing
data easy. In this exercise, you will follow the steps listed below to create
conditional and stoplight formats in Discoverer Plus. You will define a stoplight
format on profits, and you will also define a conditional format on sales revenues.
1.
To define a stoplight format on Profit
SUM, select this item and click the New
Stoplight Format
icon on the toolbar.
2.
The New Stoplight Format dialog box appears. Deselect the check box to automatically generate
the name, and enter Stoplight for Profit SUM
as the name of the format. Enter 250000
in the Unacceptable field, and 1300000
in the Desirable field. Click OK.
Note: You can also edit the default
colors of red, green, and yellow to have your own combinations of colors
to represent unacceptable, desirable, and other values.
3.
Now the worksheet with stoplights applied
on Profit SUM looks like this:
4 .
Now to define a conditional format
on Sales Revenue SUM, select this item, and click the New
Conditional Format
icon on the toolbar. The New Conditional
Format dialog box is displayed. Deselect the check box to automatically
generate the name, and enter Conditional Format
on Sales Revenue as the name. Select BETWEEN
as the condition, and enter 5000000
and 17000000 in the two fields to define
the range on values. To define the color formats, click Format.
5 .
Select colors as shown for the Text
and the Background from the color palettes,
select 14 as the Size
of the font, and click the icon
to select bold as the style. Click OK.
After applying both conditional and stoplight formats, the worksheet
will appear as shown in the image below. Note that
Americas and Europe regions are
top contributors for the sales revenues and profits in all the years.
Note: You can edit the stoplight or
conditional formats from the Format > Conditional
Formats menu option, which will open the Conditional
Formats dialog box.
6 .
Rename the sheet as Regions
Contributing to Sales & Profits at a Glance and
save the workbook.
You can add Text Area and Title to the worksheet. Also, you can insert conditional and stoplight formatting metatokens in
the Text Area or Title of the worksheet.
1.
Select the menu option
Edit > Worksheet Layout, and select the options to add a Text
Area and a Title to the worksheet
as shown in the image below. Click OK.
2.
Double-click the Title
(found at the top of the worksheet), select Text
and Background colors from the drop-down
list. Select 16 as the font size, and
select Bold as the style.
Insert Sheet Name as title, and click
OK.
Now the worksheet name is displayed as title.
3 .
Similarly, double-click the Text
Area (found at the bottom of the worksheet), and from the
Insert drop-down list select Conditional
Formats to insert conditional format metatokens. Click OK.
This helps in understanding the conditional and stoplight formats defined
in the worksheet.
The worksheet now looks like this.
Note: You can further format the worksheet
by adding formats on text, headings, and so on according to your requirements.
Enhanced Drill
Features and Parameters to Analyze Data
Using Discoverer Plus, you can now perform enhanced drill
operations such as drill to related items, drill to detail, and also drill to
links. These features are supported in the current version, in addition to the
drill up and drill down features supported earlier.
For example, in the worksheet that you created, you can drill
to product category from Year, to see what product categories have contributed
maximum to the sales revenues and profits in the Americas, Europe, and other
regions. You can also see which product categories are having high profit margins.
You can also drill to detail to see all the component rows that correspond to
a summarized value. In addition, you can drill to links, that is static URLs
(such as www.oracle.com) or you can also drill to Discoverer Worksheets. You
can also pass parameter values form one worksheet to another while defining
links. These features give you an additional edge and flexibility to analyze
data better.
In this exercise you will perform the following tasks to understand
the new features mentioned in this topic:
You have added a calculation in the previous exercise to see
profit margins for each year by region. You further want to analyze what product
categories are doing well in terms of sales revenues, profits, and also profit
margins. To drill to a related item, Product Category, perform the following steps:
1.
Open the worksheet in which you have added
My Profit Margin calculation (that is,
Regional Sales and Profits By Year-New
in this case, or open the appropriate worksheet if you have duplicated
the worksheet and saved it with a different name).
Increase the font sizes of the items in the worksheet, and also edit
the worksheet layout not to display the graph. The worksheet now looks
the image below. Right-click the drill icon
for Year. It is highlighted in the image
below.
2.
Select Drill as the option. This opens the Drill dialog box. In the Where you want to Drill to drop-down
list, select Drill
to a Related Item.
3.
From the list of items, select Product
Category to drill to this item. Click OK.
Note: Add a group sort on Year.
Also, sort Sales Revenue SUM and Profit
SUM in descending order.
4.
After drilling to product category form Year,
now the worksheet looks as shown in the image below. Note that the worksheet
also reflects the sorts that you have added in the previous step. Save
the workbook to save the changes in Regional
Sales and Profits By Year-New worksheet.
You can see that sales revenues and profits
are high for the products in the category Peripherals
and Accessories category in all the years. But you
can also see that the profit margins in the 'Photo'
category are high. Probably, as a BI Analyst, you can advise the company
to implement marketing strategies, that will rise sales revenues and
profits for the products in the Photo category,
as the profit margins are high for these products. If you observe the
data for other regions, you can see that similar trends were seen in other
regions too.
This feature enables you to see all the component rows (or
details) that correspond to a specific summarized value. For example, you have
seen that in the worksheet above, in the year 1998, the products under the Photo
category have the highest profit margin 35%.
You can see all the detail rows which correspond to this value by drilling to
detail.
1.
In the worksheet, right-click the profit margin value of 35% for the Photo category in the
year 1998. Select Drill as the option.
2.
The Drill dialog box is displayed. Select Drill
to Detail as the option from the drop-down list, and click Show
Advanced to display the advanced properties.
3 .
Select to display the component rows in a new worksheet
as a Table, and click
OK.
This will create a new worksheet with all the component rows that contributed
to the 35% profit margin in the year 1998 for the Photo category. The
worksheet displays all the detail items in the business area. A portion
of the worksheet is shown below.
Note:
You can now browse through the worksheet data using the scroll bars, without
losing the sight of the column or row headers. This is especially
helpful when you are working with large tables or crosstabs. Browse through
the worksheet that you created in this exercise to see the advantage of
this enhancement.
Earlier versions of Discoverer Plus supported parameters.
Parameters are useful to dynamically filter the data in the worksheet. In the
current version Of Discoverer Plus, you can define cascading parameters,
wherein the available values for the second parameter depends on the values
that you select for the first parameter. For example, you can define two parameters
as cascading parameters, one based on Product Category and another based on
Product Subcategory, so that the list of product subcategories will be based
on the value that was selected for the product category.
In this exercise, you will first create a new crosstab worksheet,
and then you will define cascading parameters.
Note: Creating a crosstab worksheet is not a mandatory step for defining
parameters.
1.
Add a new crosstab
worksheet to the workbook with Product
Category and Product
Subcategory as the page
items, Year
and Channel
Desc as the row
items, and Sales
Revenue SUM, Profit SUM, My Profit Margin
as the data points.
The following screenshots will help you create this worksheet:
In the Worksheet Properties page, rename this worksheet as
Channel Profitability by Product Categories. Also from the Crosstab
Format page of the Worksheet Properties page, select the options
to show item
labels and heading gridlines.
Take the help of the screenshots below to do this.
Note: Also, apply the appropriate currency

Note that now the worksheet will show the data for the selected product
category and subcategory values. Save the workbook.
This new feature enables you define and drill to either static
links (such as http://oracle.com) or to Discoverer workbooks. In the Regional
Sales and Profits By Year-New worksheet, you have drilled to a related
item, Product Category.
You want to perform further analysis on which product categories
are performing better in each channel. In other words, you want to know what
is the channel profitability for each of the product categories and/or subcategories.
This analysis can be done by defining a link on Product
Category in the RegionalSales
and Profits By Year-New worksheet, and passing on product category value
as parameter to the Channel Profitability by Product
Categories worksheet.

Sharing the workbooks, and scheduling the workbooks were
supported in the earlier version of Discoverer Plus too. However, by using the
current version of Discoverer Plus, you can also share the results of a
scheduled workbook with other users. Scheduling the workbooks allows you
to schedule long-running queries, to be run at a specified time and date. This
enables you to select a time and date at which the load on the database is low,
to run your weekly and/or monthly reports. Now Discoverer Plus also gives you
the flexibility of sharing these scheduled (monthly or weekly) reports
with your managers and others.
In this exercise, you will first schedule the workbook and
then share the scheduled workbook with other users.

Select File > Schedule.
This will open the Schedule Wizard.
