Object Linking and Embedding (OLE) is the technology that allows users to create and edit documents containing items or "objects" created
by multiple applications. Typical examples of OLE objects are sound clips, spreadsheets and bitmaps, which are easily being found in the OLE
document. With OLE support, user can store and edit their CASE tool projects easily in the documents, without leaving them into separate files.
Visual Paradigm for UML is an OLE supported CASE tool, you can benefit from it by storing and editing your VP-UML project inside your
document without any trouble.
