The whole purpose of Discoverer is to help you—the business professional
—view the data you want from a database,
analyze it to support your business decisions, and create reports to keep track of things.
How Discoverer Desktop Works
We use it to view the information in your company’s databases.
The whole purpose of Discoverer is to help you — the business professional
—view the data you want from a database, analyze it to support your business decisions,
and create reports to keep track of things.
View data in a familiar format that is easy to read and understand.
Prepare reports of your analytical results and findings. Share data with others, and in other applications (such as Excel).
The Discoverer Method of Data Access
Your company’s Database Administrator identifies all
the data needed by separate business areas
—accounting, human resources, sales, manufacturing, projects, finance, and so forth.
The Database Administrator then organizes
the data for each business area.
Workbooks in the business areas contain the specific
data needed for your various analysis tasks.

Workbook Window :
The workbook window is where you will do most of your work with
Discoverer Desktop. It shows the data in the workbook.
Four Types of Display (Layout)
Table
Page-Detail Table
Crosstab
Page-Detail Crosstab
Layout Details
Table Layout
The most familiar layout for data, a table, lists data in rows and columns.
Typical data for tables includes lists, such as a mailing list of customers
sorted by zip code or customer name, lists of income or profit from various
departments, lists of products sorted by part number or part name, and so on.
Table Layout with Page Details
A table layout with page details is a table with multiple pages of data, where
each page shows various portions of the data in detail.
You set the criteria for displaying portions of data in order to see exactly what
you want on each page.
Usually you use this type of layout to study data details in a specific, recurring
way. For example, in the Video Store data you may always want to see
monthly profits per region. In that case, each page would show one region’s
profits each month.
Crosstab Layout
A crosstab, short for “cross-tabulation,” relates two different sets of data
and summarizes their interrelationship in terms of a third set of data.
Every crosstab has at least three dimensions of data—rows, columns,
and data points.
In Discoverer, crosstabs can show the interrelationships between many
dimensions of data on the various axes.
A crosstab layout has three axes: side axis, Because each axis can hold
several data items, a crosstab can display many dimensions of data.
Page Detail Crosstab Layout
A page detail crosstab layout is a crosstab with multiple pages of data,
so you can group the data on separate pages.
You set the criteria for displaying portions of data in order to see exactly
what you want on each page,
Crosstab Layout with Page Items
(a) Page Axis.
In this sample it contains a single data item--Department.
(b) Top Axis.
This top axis contains two data items--Year and Profit.
(c ) Side Axis.
This side axis also contains two data items--Region and City.
Axis Items
The page axis, top axis, and left axis on the workbook window
represent the data in your database that have a relatively few, discrete values associated with them.
Axis items represent data that you can pivot on a crosstab worksheet or that can be column headings on a table
When creating a new worksheet, you identify the data that become axis items.
Data Points
The data points of a table or crosstab are the data in the "body" of the worksheet.
Data points are the data that you want to use for analysis purposes or to see listed on a table.
v Think of a workbook as a binder file with specific data for specific tasks.
v The workbook has pages, or worksheets, that contain data for the specific tasks.
v For example, if the workbook is for sales and profit data,
one worksheet in it might be a table listing your profit for sales versus rentals.
Another worksheet might be a comparison of your profit over the last two years by sales region.
v To simulate with Excel, Excel file is Workbook and Sheets in the excel file are Worksheets

Aggregations
Mathematical functions to aggregate the data
Text Items- Such as Customer Name, the typical aggregations are Count, Max, and Min.
That is, you can count the number of text items, or find the highest or lowes
t (where A might be the highest and Z the lowest).
Numeric Data- The typical aggregations are Sum, Count, Max, Min, Average, and Detail.
For example, you can find the Sum or Average of the numeric data with the aggregation.
The aggregation in boldface type is the default.
The database administrator sets which aggregation is the default.
