 OCCI is the C++ interface to Oracle - see the "Oracle C++ Call Interface Programmer's Guide".

 There is also OCI, which is the C interface, see the "Oracle Call Interface Programmer's Guide". This is the lowest level of all the interfaces, and so exposes the most features - some of which aren't supported in OCCI, so there's some advantages to using OCI even in C++ programs. But you can get OCI handles from an OCCI object though, so you can even write hybrid code that uses the object-oriented OCCI for most of the system, but calls OCI for the more obscure features.

 There's also Pro*C and Pro*C++, but personally I'm not very keen on these (they use a precompiler step to convert custom directives to boilerplate code... but there are limitations).
