Overview
This tutorial covers how to use Oracle Business Intelligence Answers to create queries, format views, charts, and add user interactivity and dynamic content to enhance the user experience. You create queries and work with views including charts, pivot tables, and narratives. You then create selectors to drive interactivity in your Business Intelligence requests, and build a custom Dashboard to contain the requests and views you've created. Finally, you work with dashboard prompts to filter your dashboard and populate variables.
The dashboard you build in this tutorial charts sales for the last 12 months by channel, country region, and product category and provides trend analysis data as well as narrative highlights of categories that have declined in sales in the last month.
Note: If you are a Oracle employee and using the VMWare
environment, go straight to the topic called Creating
a Query and a Chart. Skip the steps in between. Make sure you have
2 GB RAM and 15 GB hard disk space. Have VMWare 1.5.x installed on your machine.
If you do not have VMWare software, download a copy of VMWare Player from http://www.vmware.com/download/player/
For all others, before starting this tutorial, you should:
1.
Have access to or have installed Oracle
10g Database.
2.
Have access to or have installed the sample schema.
This example uses the SH schema included in the Oracle10g
Database.
An ODBC data source is needed to import schema information
about a data source into an Oracle BI Server repository. To create an ODBC data
source for importing the SH schema information, perform the following steps:
1.
Click Start > Programs > Administrative Tools >
Data Sources (ODBC) to open the ODBC Data Source Administrator.
2.
Click the System DSN tab and click Add.
The Create New Data Source dialog box opens.
3.
In the Create New Data Source dialog box, select the Oracle
driver and click Finish. The Oracle
ODBC Driver Configuration dialog box is displayed.
4.
In the Oracle ODBC Driver Configuration dialog box, enter a Data
Source Name (this can be any name), select the appropriate
TNS Service Name from the dropdown list (ORCL in this
example), and enter SH as the User ID for the SH schema.
5.
Click Test Connection to open the Oracle ODBC Driver
Connect dialog box. In the Oracle ODBC Driver Connect dialog box, enter
the password SH for the SH schema and click OK.
6.
You should see the following Testing Connection message indicating
the connection is successful:
7.
Click OK to close the Testing Connection message.
8.
Click OK to close the Oracle ODBC Driver Configuration
dialog box.
9.
Verify that the SH system data source is added in
the ODBC Data Source Administrator and click OK to
close the ODBC Data Source Administrator.
Restoring the Business Intelligence Presentation Catalog and Updating Metadata
In this topic you update the Presentation catalog and copy the repository to prepare the environment for the rest of the tutorial.
To restore the Presentation Catalog, perform the following steps:
1.
Click Start > All Programs > Administrative Tools > Services.
2.
In the Services dialog
box, select the Oracle BI Presentation Server and select Action > Stop to stop the service. Also stop the Oracle BI Server. These services can be stopped in any order.
3.
Using Windows Explorer, navigate to the SetupFiles folder and copy the sh folder and its contents to <InstallDrive>:\OracleBIData\web\catalog. This is a backup of the Presentation Catalog corresponding to the Sales History content.
4.
Open <InstallDrive>:\OracleBIData\web\config\instanceconfig.xml in Notepad and edit the CatalogPath section to point to the directory you just copied. The path should be <InstallDrive>:/OracleBIData/web/catalog/sh
5.
Navigate to the SetupFiles folder and Copy sh.rpd to <InstallDrive>:\OracleBI\server\Repository.
Files ending in .rpd are metadata files, also known as repositories. The metadata contains the information that the server uses to translate from a logical query (using business terms) to one or more physical queries needed to retrieve the correct information to satisfy the request.
6.
Open <InstallDrive>:\OracleBI\server\Config\NQSConfig.ini
in Notepad and edit the repository name to point to the sh.rpd repository
you just copied. In the Repository section, enter # before
"Star" to comment out any other repository name entry. Then,
below that entry, create a new line and enter Star = sh.rpd,
DEFAULT; to point to your repository.
NQSConfig.ini is the initialization file read by the Business Intelligence Server when it starts up. It contains a number of parameters that control server settings and behavior. Right now, you are concerned with the section that tells the server which metadata repository to read.
7.
In the Services dialog box, select the Oracle BI Server and click Action > Start. Also restart the Oracle BI Presentation Server service.
8.
In a browser, navigate to http://localhost/analytics,
enter Administrator as the User ID and password, and
click Log In.
Click the Answers link to navigate to the Answers start page, and select the Sales History subject area by clicking the SH link in the Subject Areas list.
In this example, there is only one subject area, but there could be a long list, depending on the metadata that is defined in the Oracle Business Intelligence repository, which can contain multiple subject areas. Subject areas are sets of related information with a common business purpose.
2.
In the left-hand selection pane of the Answers interface, click the Plus icon next to Times to expand it. Expand the Calendar table and click the Calendar Month Desc column to add it to your query criteria, which appears in the right pane.
The query you are building has one measure and three attributes.
3.
Click the Calendar Month Name column to add it to your query. From the Products table, add the Prod Category column. Finally, add Measures > Sales Facts > Amount Sold (000). Your query should look like this:
4.
You can reorder the columns in your query by clicking and dragging them. Drag the Prod Category column in front of the columns from the Calendar table in your query. Your query criteria should look like this:
Now drag the column back to its original location.
5.
Add a saved filter to the query to limit the data to the last 12
months (based on the SH data, this will cover from January to December
2001). Under Filters in the left-hand selection pane, expand the SH
folder and click the Most Recent 12 Months. The Apply
Saved Filter dialog box is displayed.
This filter has been created and saved in a shared folder so that it can be used by other users. The filter uses a variable defined as the value of the maximum month ID, which has been created in the Oracle BI repository metadata to ensure that it is synchronized with the data.
6.
Click OK in the Apply Saved Filter dialog box to add the filter to your query.
7.
Click the Advanced tab. The Advanced tab can be
made available only to specific users. The XML fully defines the query
(including chart formats in case of charts). The SQL defines the content
of the query. Note that any query or reporting tool that can issue SQL
over ODBC connection, can issue a query to the BI server, just like
Answers. Examine the request XML that defines the view and the logical
SQL that will be issued for the query.
The Request XML defines the whole analysis, including logical SQL and views for the query. The SQL Issued field contains only the logical SQL that will be issued to the Oracle BI Server for processing. Note the saw_X column aliases, which are added automatically. Editing the logical SQL will change your view definitions.
To add a filter for the direct channel, perform the following steps:
1.
Click the Criteria tabs, using the selection pane, add Channels
> Channel Desc to your query criteria.
2.
In the criteria pane, click the Filter button on the Channel Desc column to add a filter on that column.
3.
In the Create/Edit Filter dialog box, click the All Choices link to display all values for the column.
You can also limit the list of choices by setting a match criteria using
the Match drop-down menu and entering a string, then clicking the All
Choices link. The Limited Choices link will limit choices to those that
are consistent with any pre-existing filters.
4.
Verify that the Operator for the filter is set to "is equal to / is in" and then click the Direct Sales value in the list of choices. Direct Sales is added as a value in the filter. Click OK to create the filter.
The filter is added to the existing saved filter you used earlier.
5.
Click the Delete button (with and X) on the Channel Desc column to delete it from the criteria. You are filtering on the channel, but you don't need the column in your query.
Another way to achieve this result is to CTRL-click the column in the selection pane, which opens the Create/Edit Filter dialog box with the selected column, but doesn't add the column to the query criteria.
6.
Your query criteria should look like this:
7.
Click the Results tab to view the results of your query.
Other ways to view results are by clicking the view buttons below the
tabs in the Criteria pane, or by clicking the Display Results button below
the columns in your query criteria. By default, the results are displayed
in the Compound Layout view, which contains two other views, a Title view
and a Table view. As you will see, you can delete these default views
and add other views to the Compound Layout. Later, you will add these
different types of views to a dashboard.
8.
Return to the Criteria tab and remove
the Channel Desc filter you just created by clicking the X
next to the filter in the Filters section.
To create totals and format results, perform the following steps:
1.
To open the Edit Table view for your results, click the Edit
view
icon for the Table view in the Compound Layout.
The column controls for each column are displayed with the results. Using the view-level controls, you can also set table-wide formatting properties, import formatting from other queries, and set grand totals for the entire table.
2.
Click the Total By icon above the Calendar Month Desc column to add subtotals by month to your results.
The measure is totalled each time the value in Calendar Month Desc changes. In this case, the default aggregation rule (SUM) is applied. The default aggregation rule is set in the Oracle BI repository metadata, but can be overridden using controls in the Edit Formula dialog box accessed through the Edit Formula icon in the Edit Table view or the Criteria tab.
3.
Click the Grand Total button at the view level to add a grand total to your results.
4.
In the Display drop-down menu, select Results Only to eliminate the Header Toolbars.
5.
Scroll down to the bottom of the Results pane and click the All Pages button to navigate to the end of your results. Verify that the grand total that you set for the results is present.
6.
In the Display drop-down menu, select Header Toolbars with Results to access the Header Toolbars.
7.
Click the Column Properties
icon above the Amount Sold (000) column. In the Column Properties dialog
box, click the Data Format tab, select the Override
Default Data Format option, then select Use 1000's Separator
option and click OK. This will display a comma
separator in the number results for the column.
8.
In the Edit Column Format dialog box, click the Save button. If you have permissions as a Web administrator, you can save the data format as the system-wide default for the column you are working with, or for all columns with the same data type.
Since you don't want to set this format as the system-wide default, click in the dialog box to close the Save menu.
9.
Click OK and verify that a 1000's separator is displayed in the results for the Amount Sold (000) column.
Pick Chart in the View menu. By default charts are displayed as a Vertical Bar graph.
2.
Select Line from the Graph drop-down menu and 2D from the Type drop-down menu.
3.
Under the Legends icon in the column area of the left side of the Chart view, select Prod Category to create a separate line in the chart for each product category. Click the Redraw button at the bottom to confirm the change.
The column area of the chart view shows the columns that are included in the request. You can select the columns to display as the different axes in the chart. You can also indicate whether measure labels appear for factual data plotted on an axis. The available axes can change depending on the type of chart selected from the Graph drop-down list.
4.
Click the Axis Titles and Labels
icon. In the Left tab of the Axis Titles & Labels
dialog box, select Custom Title and change the custom
title to Amount Sold. In the Bottom tab,
change the custom title to Calendar Month.
5.
Explore some of the other options in the Axis Titles & Labels dialog box. For example, you can toggle whether scale labels are displayed on the axes and set orientation guidelines for your labels. In addition, you can set overrides for the default data format on measures, similarly to the modification you made to the amount sold column in the steps above. Click OK. Your chart should look like this:
6.
Click the General Chart Properties icon. In the General dialog box, select Custom Title, enter Category Sales Last 12 Months as the chart title, and click OK.
7.
Click the Additional Charting Options icon. In the Additional Charting Options dialog box, click the Borders & Colors tab and set the background color to light gray. Click the color box for Background Color and, in the Color Selector dialog box, select light gray from the pallette and click OK.
.
8.
In the Additional Charting Options dialog box, click the Grid Lines tab and set the major grid line color to white and the minor grid line color to light gray, using the same method as above. After you've set both colors, click OK to apply your changes.
Your chart should look like this:
9.
Sort the legend by sorting the data. You want to sort by month in ascending order and then by sales in the last month in descending order:
a.
Click the Criteria tab and add the Measures > Sales Facts Current Month > Amount Sold (000) Current Month column to your query.
b.
Click the Order By button in the Calendar Month Desc column. The arrow points up to indicate an ascending sort.
c.
Click the Order By button in the Amount Sold (000) Current Month column twice. The arrow points down to indicate a descending sort, and the number 2 is displayed to indicate a secondary sort.
10.
Click the Results tab to verify that your sort has been applied to the legend in your chart. The legend is sorted to match the order of the lines in the last month.
11.
Select Compound Layout from the View drop-down menu.
12.
Click the Add View link and select Chart
to add the Chart view to the Compound Layout view.
13.
Scroll to the bottom of the Compound Layout view and drag the Chart view above the Table view in the Compound Layout. A yellow line will appear when you have a valid insertion point.
14.
Click the Delete View icon in the Title view to delete it from the Compound Layout.
15.
Click the Save Request
icon. In the Choose Folder dialog box, click Shared Folders,
then click the Create Folder button. In the Create Folder
In Shared Folders dialog box, enter Learn and click OK.
16.
In the Save Request dialog box, click the Learn folder.
Enter Category Sales as the name and click OK.
To create and set the basic layout for a pivot table, perform the following steps:
1.
Pick Pivot Table in the View menu. This opens the Pivot Table Layout page.
2.
Examine the default pivot table that's created and displayed below the layout controls. Measure labels for the measures in your query appear in blue as columns in the pivot table. Row headings for the dimensional attributes in your query are displayed in grey as rows by default. The measures are displayed at the intersection of the rows and columns.
3.
Deselect the Display Results option. This option displays the results of any layout modifications you make as you work in the Pivot Table layout. To speed performance, you will only view your results periodically.
4.
Drag the Amount Sold (000) Current Month column from the Measures area to the Excluded area in your layout controls. When you see a blue line appear around the control, you have a valid insertion point and can drop the column.
5.
Drag the Calendar Month Desc column below the Measure Labels in the Columns area in your layout controls. When you see a blue line appear, you have a valid insertion point and can drop the column.
6.
Drag the Calendar Month Name column below the Calendar Month Description in the Columns area in your layout controls. Click the Disply Results link to verify your changes in the pivot table.
To add calculations and formatting to the pivot table, perform the following steps:
1.
You need to add a measure to your pivot table to display the percentage
of total monthly sales for each product category. Duplicate the Amount
Sold measure. Click the More Options
icon in the Amount Sold (000) measure and select Duplicate Layer.
2.
Click the More Options icon in the duplicated measure
and select Format Headings.
3.
In the Edit Format dialog box, change the caption to % of
Period and click OK.
Also note the other formatting options available in the dialog box.
4.
Click the More Options icon in the duplicated measure
and select Show Data As > Percent of > Column.
This setting means that the measure will be displayed as a percentage
of the column, which is Month. Note the other options that are available;
you can present a measure as a percentage of the total amount for any
dimension present in the pivot table layout, for example a row or a section.
You can also set alternate aggregation rules for the measure using the
Aggregation Rule option (the default is Sum).
5.
To total the values of the rows in each column, click the Total
icon
in the Rows layout control and select After.
Note that you have formatting options available for the total row labels
as well as values.
6.
To add totals for each column in each row, click the Total
icon in the Columns layout control and select After.
7.
Click the click the More Options
icon in the Calendar Month Desc column and select Hidden.
8.
To show both measures together within each calendar month, drag Measure
Labels under Calendar Month Name in the Columns layout control.
9.
Click the Display Results link. Your pivot table should
look like this:
Note that there are section and page levels of the pivot table that we
have not used in this example. Effective use of these would require additional
attributes. Experiment, if you want, by temporarily dragging Prod Category
to section and then page.
10.
Save the request by clicking the Save Request
icon.
In this topic you build and format a business intelligence request using Oracle BI Answers, and create and format a Narrative View. The Narrative view allows you to add text to appear with the results to provide information such as context, explanatory text, or extended descriptions.
Click Answers to navigate to the Answers start page, and select the Sales History subject area by clicking the SH link in the Subject Areas list.
You want a query to detail what happened in the most recent month, pointing out all product categories where sales are less than the previous month.
2.
In the left-hand selection pane of the Answers interface, expand the Products table and click the Prod Category column to add it to your query criteria.
3.
Add Measures > Month Ago Facts> % Chg Amount Sold MAgo
to your query . Your query should look like this:
4.
Add a saved filter to the query to limit the data to the current
calendar month. Under Filters in the left-hand selection pane, expand
the SH folder and click the Current Calendar
Month filter. Click OK.
This filter has been created and saved in a shared folder so that it can be used by other users. The filter uses a maximum month variable defined in the Oracle BI repository metadata to ensure that it is synchronized with the data.
To create a narrative view, perform the following steps:
1.
Select Narrative from the View drop-down menu.
2.
In the Narrative view workspace, enter the following: @1 declined @2% this month compared with last month in the Narrative field.
The narrative is a combination of text and query column values. In this example, @1 refers to the first column in the query, Prod Category, and @2 refers to the second column, % Chg Amount Sold MAgo. Note that you can control the number of row values returned in the Narrative view by setting the Rows to display value. By default, all queried rows are displayed.
3.
To highlight the column values in the narrative, select @1 in the narrative and click the Bold button. Also add bold tags to @2%.
Your results should look like this:
4.
Select No Results from the View drop-down menu. You need to create a No Results view to appear when there are no results for the query.
5.
In the No Results view workspace, enter No categories declined this month! as the headline. Enter All categories had positive sales results compared with the previous month as text.
Your results should look like this:
6.
Click the Save Request icon. In the Choose Folder dialog box,select the Learn folder and save the request as Narrative and No Results Views.
In this topic you build Column and View
Selectors and experiment with their use in requests and dashboards. Column selectors
allow users to select from a group of columns, substituting columns in their
queries for comparative analysis. View Selectors allow users to quickly navigate
between different views of their queries, for example viewing different charts
of the same data or quickly navigating to a pivot table to do trend analysis.
To create a Column Selector, perform the following steps:
1.
Click the Answers link and open the first query you
saved. In the selection pane, click Shared Folders > Learn
> Category Sales.
2.
Click the Modify button.
3.
Click the Results tab and select Column Selector
from the View drop-down menu.
4.
Select the Include Selector option in Column 3, currently
Prod Category.
5.
In the selection pane, click the following columns to make them available
in the Column Selector: Customers.Country Region, Customers.Country,
and Channels.Channel Desc.
Your Column Selector in the results pane should look like this:
6.
Select Compound Layout from the View drop-down menu.
7.
Click the Add View link and select Column
Selector to add the Column Selector view to the Compound Layout
view.
Notice that views that you have built for the active request appear in
the View and Add View drop-down menus with green circle icons next to
them.
8.
Scroll to the bottom of the Compound Layout and drag the Column Selector
view above both Table and Chart views.
9.
In the Column Selector, select Country.
10.
Your Compound Layout view should look like this:
Note that the third column in the table now reflects values for the Country
column, as does the chart. Switch the column back to Channel Desc.
Save the request.
To create a View Selector, perform the following steps:
1.
Duplicate the existing chart:
a.
Using the Views menu, navigate to the Chart view.
b.
Click the Menu icon and select Duplicate View.
You should now have a new view, Chart:2:
c.
In the Type drop-down menu, select 3D.
2.
Select View Selector from the View drop-down menu.
3.
In the View Selector design workspace, select Chart, Chart:2, and Pivot Table in the Available Views field, using CTRL + Click to select multiple views.
Click the Move Right icon to add them to the Views Included field.
4.
Select Chart in the Views Included field, click the Rename button, and, in the Rename dialog box, rename it 2D Chart. Click OK.
5.
Rename Chart:2 as 3D Chart and Pivot Table as Trend Data. Use the Move buttons to arrange the views in the list as follows: 2D Chart, 3D Chart, Trend Data.
