AcAcronym for Dynamic Data Exchange, an interprocess
communication (IPC) system built into the Macintosh,
Windows, and OS/2 operating systems. DDE enables two
running applications to share the same data. For example,
DDE makes it possible to insert a spreadsheet chart into a
document created with a word processor. 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.
