Hi Purnima..

Linking Objects:

The first OLE method, linking, allows the user to share information among applications by creating a connection (or link) between the original source document and the destination document. If the source is altered after an OLE has been established, the destination document will automatically update and show all the changes that have been made. When data are linked between two documents in this way, the data are not actually stored in a destination file. The destination document stores only the information it needs to link back to the original source document. If changes need to be made to the linked information, the changes must be made and saved in the original source application.

One important point to remember when linking information is that the destination document must always be able to locate the original source document. If a destination file was copied to a floppy disk and taken to another computer, all linked files must also be copied onto the floppy disk in order for the links to be able to find their connections.

Embedding Objects:

The second type of OLE process, embedding, is another feature of Windows. When information from one application is embedded into another, the information becomes part of the destination file. Although this process requires the use of more memory, it allows the destination file to be self-supporting. When the embedded object needs to be edited or updated, the user must double-click on the object. This double-clicking opens the source application file inside an editing window. All the necessary menus and features will be available in this window for use in editing the source information. After making the appropriate changes to the embedded object, the user simply clicks outside of the editing window and returns to the destination document. Because the user does not have to keep opening and closing the source application file, a great deal of time is saved. Another advantage of this feature is that the user can make changes in the embedded object and the destination file without touching the original source document and vice versa. In keeping with linking objects, the user must be able to access all source applications in order to make changes in any embedded objects. The user does not, however, need to have access to the original source application in order to print or view the destination document. To embed an object, the user follows the same procedures as for linking an object except that in the Paste special menu the Paste option is selected instead of the Paste Link option.
