Line 9:

[[Oracle Corporation]] first released OCI (under the name HLI, the Host Language Interface) with Oracle Database version 6 in 1988. As HLI (and subsequently OCI) operated as wrappers for UPI, their original naming conventions closely resembled those of the UPI calls they were based upon. For example, the [[Rollback (data management)|rollback]] statement: the call <code>upirol</code> in UPI became <code>orol</code> in OCI.

Later, in Oracle8 (released in 1997), OCI calls acquired more descriptive names; <code>orol</code> became <code>OCITransRollback</code>. Subsequent improvements have been made in every version of OCI, including 11g (released in 2007). Oracle Corporation [http://www.oracle.com/technology/tech/oci/index.html claims] that OCI is "So reliable that every SQL statement in the Oracle Database executes with OCI".<ref>http://www.oracle.com/technology/tech/oci/index.html</ref>
