【OLE vs. Active Technology】
OLE vs. Active technology: The name OLE denotes the technologies associated with linking and embedding, including OLE containers, OLE servers, OLE items, in-place activation (or visual editing), trackers, drag and drop, menu merging. The term Active applies to the Component Object Model (COM) and COM-based objects such as ActiveX controls. OLE Automation is now called Automation.
【Compound document vs OLE document】
OLE documents, historically called compound documents, seamlessly integrate various types of data, or components. Sound clips, spreadsheets, and bitmaps are typical examples of components found in OLE documents. Supporting OLE in your application allows your users to use OLE documents without worrying about switching between the different applications; OLE does the switching for you.
