1 Object Linking and Embedding Objective 6.02 Linking and Embedding

2 Linking  A linked object maintains a connection between two files—the source file it is created in and the destination file it is inserted into.  The linked object in the destination file can be updated when the source file is updated.

3 Linking  External reference: A reference to a cell or range of cells on a sheet in another Excel workbook, or a reference to a defined name in another workbook.  A link can also be made to another program, and this link is sometimes called a remote reference.

4 Linking  Because data in another workbook or program may change and outdate the data in your workbook, there are options for controlling the updating of links.  Linking is especially useful when it is not practical to keep large worksheet models together in the same workbook.

5 Embedding  Information (an object) that is contained in a source file and inserted into a destination file.  Once embedded, the object becomes part of the destination file. Changes you make to the embedded object are reflected in the destination file.

6 When to use linked objects  Use linked objects when you want the information in your destination file to be updated as the source data changes.  The linked information is updated automatically if you change the original data in the source file.  For example, a range of cells in a Word document that is linked to and exists in an Excel workbook will automatically be updated as the Excel workbook is edited.

7 When to use Embedded objects  Use an embedded object when you don't want to update the copied data as it changes in the source file.  The version of the source is embedded entirely in the workbook.  Because an embedded object has no links to the source file, the object is not updated if you change the original data.

8 What is the difference?  Linked object: Linked to the source file.  Embedded object: No connection to the source file.  Source file: Updates the linked object.
