Business Object Base classes

This section describes the business object base classes which will be used to derive new business objects.

The core base class is wwBusiness which in turn contains an instance of a wwData derivative (wwSQLData for example) to handle the actual back end data access. These classes here, especially wwBusiness, are important as the methods exposed by wwBusiness are exposed to all the business object classes.

To use the classes please also refer to the Creating new Business Objects topic.
