OBJECT LINKING EMBEDDING IN MULTIMEDIA


What is OLE?


The full name of OLE is object linking & embedding. This means linking the object of one application to another application. It has been developed by Microsoft which is based on the Components object Model (COM).


"OLE is a Microsoft technology through which we can dynamically link files and applications together ."


Linking establishes a connection between two objects, and the embedding application facilitates data insertion. Thus OLE means a technology that links the object of the application to another application. OLE is used for applications data transfer via compound document management as well as drag-and-drop and clipboard operations.


for example:-


  • We can link MS Excel sheets in MS Word when the spreadsheet is opened in Word then the user interface of the spreadsheet is loaded. And inside the word document, we can work on Excel.
  • Through this, we can open an image/picture in a photo editing program like - Photoshop, move it to word, excel, or any other application.

OLE was later developed into a much larger standard called COM (components object model). COM is supported by MAC, UNIX, and Windows systems. But it is mainly used in Microsoft Windows. COM is the foundation of ActiveX through which developers create interactive content for the web.


OLE-supported software applications


  • Microsoft Windows applications like– Excel, Word, and PowerPoint
  • Corel WordPerfect
  • Adobe Acrobat
  • AutoCAD
  • Multimedia applications, like– photos, audio/video clips, and PowerPoint presentations.

Disadvantage of OLE


  1. Embedded objects increase the size of the host document file causing storage and loading problems.
  2. Linked objects can break if linked objects are placed in a location where the original document application is not present.
  3. If the linked and embedded object application is not available, then you cannot edit and manipulate the object.
