DDE (Dynamic Data Exchange), a communication protocol that let applications call each other.OLE was the first protocol that enabled users and programmers to create compound documents—that is, documents that contain data from different applications (for example, an Excel worksheet inside a Word document). Depending on the application's needs, compound documents can completely encapsulate other simpler documents (embedding) or contain simply a reference to existing documents (linking). When the user clicks on an embedded or linked document inside a compound document, Windows runs the application that's capable of dealing with that particular type of document.
