Oracle C++ Call Interface (OCCI)

Oracle C++ Call Interface (OCCI) is the native C++ language API for accessing Oracle Database directly from C++ applications. Very similar to the OCI, OCCI supports both relational and object-oriented programming paradigms.

The OCCI Software Development Kit is also installed as part of the Oracle Instant Client, which enables you to run applications without installing the standard Oracle client or having an ORACLE_HOME. Your applications work without change, using significantly less disk space.
