Oracle Call Interface (OCI)

Oracle Call Interface (OCI) is the native C language API for accessing Oracle Database directly from C applications.

The OCI 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.
