ClearBI is a Web reporting component and a business intelligence engine that allows software developers as well as the end users to automate the reporting process.
There are two versions of ClearBI: Developer Edition and Server Edition.
ClearBI Developer Edition allows software developers to visually create and customize reports in Eclipse IDE. The report layouts are captured in MXML and can be compiled and integrated into any Flex application. The end users will be able to work with report (sorting, filtering, grouping, export to Microsoft Excel, et al.), but won't be able to save the customized report.
ClearBI Server Edition delivers all the functionality of the Developer Edition to the end user; it allows the end users to create reports from the universe of the data fields without need to install any software other than Flash Player. The end users can create, customize and save reports in the centralized database server without any help from the IT department.
