Microsoft SQL Server Report Builder
Report Builder is a report authoring tool within Microsoft SQL Server that features a Microsoft Office-like environment, giving the business user the possibility to author existing reports or create new ones. All the objects such as tables, tablix, spark lines, gauges, … from Reporting Services are available for the business user and can be used in a user-friendly environment.
