Table Layout The Four Types of Display

2-4 Oracle Fusion Middleware Users Guide for Oracle Business Intelligence Discoverer Desktop customer name, lists of income or profit from various departments, lists of products sorted by part number or part name, and so on. Here is a sample of a table layout on the workbook window. As you can see, it is essentially a listing of data. Figure 2–3 Table Layout

2.2.1.1 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.

2.2.2 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. For example, a typical crosstab for a chain of retail business stores might show the monthly total sales by products by store. In other words, there are three sets of original data: each store name, product type, and total sales amounts. The store name and product type are axes of the crosstab as rows and columns. Each row and column intersection shows the data points, in this case the total sales for a store and product type. Every crosstab has at least three dimensions of data—rows, columns, and data points. But in Discoverer Desktop, crosstabs can show the interrelationships between many What You See on the Screen 2-5 dimensions of data on the various axes. A crosstab layout has three axes: side axis, top axis and page axis. Because each axis can hold several data items, a crosstab can display many dimensions of data. For example, the following figure is a sample crosstab that shows five dimensions of data: regions and city names, year, department video rentals and video sales and the total profit. In this example, the data points that is, the intersections, or cells on the crosstab are the sums for total profit. The next page of data would show the same type of data, except for the next department, which is Video Sale. Figure 2–5 Crosstab Layout with Page Items
