This demo illustrates how to design an ORMapping on top of the Microsoft demo database "Northwind". The mapping file is NorthwindMapping.xml. In this database, most of the mapping is very straight forward. Most classes have a simple one column primary key, and no classes require any secondary keys. The class OrderDetail has a compound key made up of the two relations to Order and Product.

The demo requires MS SQL Server and that the Northwind database is installed. This database is installed as a part of SQL Server Personal Edition (and higher editions), but not in MSDE (Desktop Edition).

Compile and run the application.

• The main window will show the listings of three classes.
• The autoform is enabled for all three grids, so you can navigate the objects by double clicking the left most column (the gray one).
• If you make changes to objects or create new objects, you can save the modifications by clicking the UpdateDB button on the main form
