Data Source Manager

The Source Manager provides the communication path between the Application and the Source, supports the user’s selection of a
Source, and loads the Source for access by the Application.
Communications from Application to Source Manager or the Source to Source Manager (via DAT_NULL) arrive in exclusively through the DSM_Entry() entry point.
