A broad range of customers including Fortune 500 customers and ISVs develop high performance applications directly in OCI.
OCI is highly reliable. Oracle tools such as SQL*Plus, Real Application Testing (RAT), SQL*Loader, and Data-Pump all use OCI. OCI also provides the foundation on which other language-specific interfaces such as Oracle JDBC-OCI, Oracle Data Provider for Net (ODP.Net), Oracle Precompilers, Oracle ODBC, and Oracle C++ Call Interface (OCCI) drivers are built. OCI is also used by leading scripting language drivers such as PHP OCI8, ruby-oci8, Perl DBD::Oracle, Python cx_Oracle, and the statistical programming language R's ROracle driver.
OCI libraries are included by default in Oracle Database 12c. OCI is also in the lightweight Oracle Instant Client, allowing ISVs and customers to quickly install and deploy OCI applications and tools. See the Oracle Instant Client page for more information.
