You data bind to the properties of the bizobj and then provide an Update method for updating the fields from the properties. In this scenario the interface controls are not directly altering the fields, they are altering properties of the bizobj, the buzobj will update the tables when its update method is called.

This thread is most instructive. Where do you put your field-level validationand/or field-level security using this approach (and VFP 5.0)?

I prefer this to the individual properties approach because a generic bizobj can hide a lot more of the functionality thus reducing the code added to each specific bizobj class definition.
