Another way may be to create objects in a data driven way to hold detail and totals in nicely named properties, and them save the properties in a single memo field in XML form or as a data array. In order to save time in object creation I would like to create a master object and then clone it each time.

I have been trying to stay away from memo fields. VARCHARs instead....
