SUN Report Builder/Example
From Apache OpenOffice Wiki
Data Model
The example will use a very simple, and common, data model. Two tables, one a list of products and the other a list of the cost for multiple purchases of each product. Referred to as One to Many ( 1..n) relation.

The report will display all cost records for each product, and group by the product name. Therefore a query is used to put the data from the two tables into one contiguous result set, for use by the report builder.
Report layout - User defined functions
The Sun Report Builder allows creation of user defined functions at two levels. The report level and the group level.
