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.

Products Table ( Table2 )

ProductID
ProductName
0
Apples
1
Oranges
2
Grapes
3
Melons

Product Cost Table ( Table1 )

ProdID
Cost
0

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.
