Procedure for the program overlapping data exchange for Windows (from version 3.0). Between two different applications data are exchanged by copying a file of the source application (server program) completely or partly to the target application (client program). There is, however, still a connection between the copy and the source element so that modifications in the source element are transmitted to the copy. Later DDE was substituted and extended by
OLE. The OLE procedure, linking objects, corresponds essentially to the DDS procedure.
