This document explains how to install, configure, and use Oracle Objects for OLE (OO4O). It covers features of Oracle Database that apply to Microsoft Windows operating systems.

Oracle Objects for OLE (OO4O) allows easy access to data stored in Oracle databases with any programming or scripting language that supports the Microsoft COM Automation.


Oracle Database 11g Release 2 (11.2) is the last database version that supports Oracle Objects for OLE. Oracle Database versions, which are released after Oracle Database 11g Release 2 (11.2), will not support Oracle Objects for OLE. You can continue to use Oracle Objects for OLE with existing Oracle Database versions that are covered under the lifetime support policy of Oracle.


Oracle Objects for OLE Developer's Guide is intended for programmers developing applications to access an Oracle database using Oracle Objects for OLE. This documentation is also valuable to systems analysts, project managers, and others interested in the development of database applications.

To use this document, you must have a working knowledge of application programming using Visual Basic or Microsoft C/C++ and knowledge of Component Object Model (COM) concepts.

Readers should also be familiar with the use of structured query language (SQL) to access information in relational database systems.
