Reporting Services Deep Dive

SQL Server 2008 Reporting Services Deep Dive

Agenda

• Reporting Services 2008 Architecture• Report Engine Improvements• Report Rendering Improvements• Memory Management• New Controls

- Tablix [demo]- Charts and Gauges [demo]

• Report Builder 2.0 [demo]

Benefits of Eliminating IIS from SSRS Architecture• Easier configuration

- IIS settings for other applications impact SSRS.• Better resource management

- IIS is designed for static or dynamic HTML pages and not for executing large reports for many concurrent users.

- Memory management is easier to implement outside of IIS and can be efficiently managed.

• Consolidation of two services into one- Communication process between services is now eliminated.

• Elimination of deployment obstacles- SQL Server DBAs lacking IIS skills.- IT policies prevent IIS and SQL Server on same server.

Reporting Services 2008 Architecture


Report Engine Improvements

• On-demand processing of reports with many datasets and data regions

• Reports with heavy usage of interactivity can be significantly faster

• Faster page-by-page navigation when viewing reports interactively

• Smaller memory footprint

You probably now think -- thanks that’s nice; and where is the catch?

Rendering Improvements• CSV Renderer redesign

- True data renderer, not a combination of data and layout- Removing the layout information means the data output file can be

consumed more readily by other applications.

• Excel Renderer- Supports rendering of subreports and nested data regions

17


New Word Renderer

18

• Output RDL to Microsoft Word binary format (.doc)• Support for Word 2000 and later• Documents fully editable in Word


Rich Text Formatting

• Apply different format properties to selected text within a textbox

- Font settings: Color, Font, TextAlign

- Paragraph settings: Indent, SpaceAfter, SpaceBefore- List settings: ListLevel, ListStyle

• Use HTML tags in selected text- Action: HTML – Interpret HTML tags as styles
