What is OLE? Explain.

Answer Posted / baljeet deshwal

object Linking and Embedding (OLE) is a distributed object system and protocol developed by Microsoft. OLE allows an editor to "farm out" part of a document to another editor and then reimport it. For example, a desktop publishing system might send some text to a word processor or a picture to a bitmap editor using OLE. The main benefit of using OLE, next to reduced file size, is the ability to create a master file. References to data in this file can be made and the master file can then have changed data which will then take effect in the referenced document.Dynamic Data Exchange (DDE) is a technology for communication between multiple applications under Microsoft Windows and also OS/2. Although still supported in even latest Windows versions, it has mostly been replaced by its much more powerful successors OLE, COM, and OLE Automation. However, it is still used in several places inside Windows, e.g. for Shell file associations.
