The DataModRef object points to preprogrammed data access components stored in a data module. If you maintain data access code in a data module, then you can use a DataModRef object to return rowsets in place of a Query or StoredProc component.

Data modules offer convenient reusability and easy maintenance of data access code. By storing custom or preset data access components in a data module, it is easy to maintain them (change links to changing databases, for example). Then, you can use just the DataModRef component (or custom class) to instantly implement the full set of current data access components.

To set a DataModRef object to point to a data module, set its filename property to the path name of the data module.
