BIRT Top Customers Report

Virgil Dodson

A report against the "Classic Models Inc." sample database making use of the top n and top percent filter capabilities, the report shows a bar chart with the top N customers by revenue, followed by a listing of the top M% customers by revenue sorted by customer name. This requires multiple passes over the data, but it is all done "under the covers" by the BIRT report engine. N and M are passed into the report as parameters to allow report users to select the number and percentage at run time. Created with BIRT 2.0.
