Object Linking and Embedding (OLE)

Object linking and embedding (OLE) allows information from another source document to be imported into a destination document.
There are two import options available: linking and embedding.

LINKING:
When linking, information that is linked to a source document is displayed in a destination document. The linked information remains stored in the source document, while only a link to this information exists in the destination document. When the source document is changed, the linked information in the destination document is automatically updated with the changes.

EMBEDDING:
When embedding, information that is not linked to its data source document is inserted into a destination document. The embedded information, or object, is actually stored in the destination document. When the embedded object is double-clicked in the destination document, the data source application in which the embedded object was created opens within the destination document, allowing the embedded object to be edited directly in the destination document.
