Oracle Instant Client enables development and deployment of applications that connect to Oracle Database, either on-premise or in the Cloud. The Instant Client libraries provide the necessary network connectivity and advanced data features to make full use of Oracle Database. The libraries are used by the Oracle APIs of popular languages and environments including Python, Node.js, Go, PHP and Ruby, as well as providing access for Oracle Call Interface (OCI), Oracle C++ Call Interface (OCCI), JDBC OCI, ODBC and Pro*C applications. Tools included in Instant Client, such as SQL*Plus, SQL*Loader and Oracle Data Pump, provide quick and convenient data access.
