2.2.11 About style sheets

Style sheets or Cascading Style Sheets refer to HTML extensions that provide powerful formatting flexibility. With style sheet support, your HTML documents can include any of the following: ■ any font size or style ■ overlapping objects ■ horizontal and vertical lines and rectangles of any color or width ■ precise object positioning on a page ■ pagination ■ printing from a Web browser ■ inline image maps This means that the sophisticated formatting in a report is preserved when you format the report as an HTMLCSS document. Without style sheet extensions, your HTML documents display only basic text formats and imported images. With style sheets, images of highly formatted text can be replaced with text objects of equivalent style, color, and font. Text objects can be positioned to overlay image objects. All text is fully searchable, and fewer images have to be downloaded. To view an HTML document that takes advantage of style sheets, you must display it in a browser that supports style sheets. Advanced Concepts 2-15 Using external style sheets for HTMLCSS output Every corporate Web site today uses style sheets to enforce the corporate look-and-feel across Web pages. External style sheets are Cascading Style Sheet CSS files that are referenced by these Web pages. End users typically want the same style used in pages on their Web site applied to their Web reports. In prior releases, applying style sheets and user-defined styles to reports involved manually editing the HTMLCSS output. You can specify user-defined styles and style sheets for HTMLCSS output using Oracle Reports Builder. Styles can be applied to report, field, text, frame, and repeating frame objects using the new properties Style Sheets, CSS Class Name, and CSS ID properties see the Oracle Reports online Help for descriptions of these properties. The generated HTMLCSS output includes links to the style sheets and the user-defined styles are applied to the objects. Restrictions The following elements are not supported by HTML style sheet extensions: ■ ellipses, arcs, polygonspolylines, and diagonal lines ■ rounded rectangles formatted as rectangles ■ arrows on lines ■ dashes on lines or borders of objects See also Section 4.7.16.4, Displaying report output in your Web browser Section 4.7.17.3, Printing a report from your Web browser

2.3 Data Model Objects

The topics in this section build on the basic concepts discussed in Section 1.7, Data Model Objects . ■ About summary columns ■ About formula columns ■ About placeholder columns ■ About referencing columns and parameters ■ About non-linkable queries ■ About links versus groups ■ About matrix objects

2.3.1 About summary columns

A summary column performs a computation on another columns data. Using the Report Wizard or Data Wizard, you can create the following summaries: sum, average, count, minimum, maximum, total. You can also create a summary column manually in the Data Model view, and use the Property Inspector to create the following additional summaries: first, last, standard deviation, variance. If your report requires a customized computation, for example, one that computes sales tax, create a formula column see Section 4.8.10, Creating or editing a formula column .
