Object Linking and Embedding Objective 6.02 Linking and Embedding
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.
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.
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.
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.
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.
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.
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.
