An IDetailTracker object provides a series of methods. Using these methods together with the ISqlModelMapper.TrackMaster method can easily track and save data in the models with complex multi-level relationship such as master-detail or master-detail-granddetail. The IDetailTracker object currently supports up to three levels of master-detail relationships (master-detail-granddetail).
