Object Linking and Embedding (OLE) is a proprietary technology developed by Microsoft that allows embedding and linking to documents and other objects.
The Object Linking and Embedding (OLE) Data Structures allow data from one application to be stored in the document of another application. The first application is called the creating application and the second application is called the container application. The data itself is called an embedded object.
The OLE File Format Data Structures also allow a document from one application to reference data that resides in a different application. The first application is called the container application and the second application is called the creating application. The data being referenced is called a linked object.
