To create an MTS data module at design time, choose File|New|Other, and select Transactional Data Module from the multitier page of the new items dialog. If you are writing the application server in Delphi, the Transactional Data Module Wizard then
creates a new descendant of TMtsDataModule that supports an interface that descends from IAppServer.
