What is Oracle Objects for OLE?

Oracle Objects for OLE (OO4O) is a middleware product manufactured by
Oracle Corporation that allows native access (no ODBC) to Oracle databases from
client applications via Microsoft OLE (Object Linking and Embedding) and COM.

One can bind grids, text box widgets, and so on to OO4O via its own Data Control,
one can also create dynasets, execute stored procedure code, or just about any
other Oracle command one can think of. Oracle Objects consists of the
following three components:

• An OLE 2.0 Automation (InProcess) Server - This provides an OLE Automation interface to applications that support
  OLE automation scripting such as Visual Basic (VB).
  
  
• An Oracle Data Control - This is the Visual Basic custom control (VBX).
  
  
• Two C++ Class Libraries - C-Libraries for Microsoft Foundation Classes (MFC) and Borland (OWL).
