Acronym for Dynamic Data Exchange, an interprocess communication (IPC) system built into the Macintosh, Windows, and OS/2 operating systems.

Whenever the spreadsheet data changes, the chart in the document changes accordingly.
Although the DDE mechanism is still used by many applications, it is being supplanted by OLE, which provides greater control over shared data.
